Bryophyte Generations
Tracheophyte Generations
 The way in which the alternation of generations occurs in plants depends on the type of plant. In bryophytes (mosses and liverworts), the dominant generation is haploid, so that the gametophyte comprises what we think of as the main plant. The opposite is true for tracheophytes (vascular plants), in which the diploid generation is dominant and the sporophyte comprises the main plant. Bryophyte Generations
Bryophytes are nonvascularized plants that are still dependent on a moist environment for survival (see Plant Classification, Bryophytes . Like all plants, the bryophyte life cycle goes through both haploid (gametophyte) and diploid (sporophyte) stages. The gametophyte comprises the main plant (the green moss or liverwort), while the diploid sporophyte is much smaller and is attached to the gametophyte. The haploid stage, in which a multicellular haploid gametophyte develops from a spore and produces haploid gametes, is the dominant stage in the bryophyte life cycle. The mature gametophyte produces both male and female gametes, which join to form a diploid zygote. The zygote develops into the diploid sporophyte, which extends from the gametophyte and produces haploid spores through meiosis. Once the spores germinate, they produce new gametophyte plants and the cycle continues.

 Bryophytes are dependent upon the moisture in their surroundings for both reproduction and fluid transport. The flagellated male gametes of bryophytes, like those of their aquatic ancestors, rely on water to help them move toward female gametes. Additionally, because they lack the efficient system of internal fluid transport found in tracheophytes, bryophytes require environmental moisture to ensure that all parts of the plant remain nourished. Like all plants, the bryophyte life cycle goes through both haploid (gametophyte) and diploid (sporophyte) stages. The haploid gametophyte comprises the main plant (the green moss or liverwort), while the diploid sporophyte is much smaller and is attached to the gametophyte. The haploid stage, in which a multicellular haploid gametophyte develops from a spore and produces haploid gametes, is the dominant stage in the bryophyte life cycle. This stands in direct contrast to the tracheophyte life cycle, in which the diploid stage is dominant. For more information about the life cycles of bryophytes and tracheophytes, see Alternation of Generations. Mosses
Together, mosses and liverworts comprise most of the phylum Bryophyta. Each moss sporophyte consists of a foot, stalk, and sporangium-containing capsule that extends outward from the "leafy" gametophyte plant.

 Since bryophytes do not depend on root structures for nutrient uptake like vascular plants, they are able to survive in environments that vascular plants cannot (e.g., on the surface of rocks). All bryophytes have a dominant gametophyte stage in their life cycle. During this stage, the plant is haploid and the sex organs that produce the gametes are developed. Bryophytes are unique compared to many other plant species in that they remain in this stage for long periods. The sporophytes (the diploid form of the plant) of bryophytes are unbranched, producing a single spore-producing capsule ( sporangium ). Moreover, the sporophytes are dependent on the gametophyte for nutrition and develops within the female sex organ (archegonia). Bryophyte Life Cycle
The bryophyte lifecycle consists of alternating generations between the haploid gametophyte and the diploid sporophyte. During the gametophyte stage, haploid gametes (male and female) are formed in the specialized sex organs: the antheridia (male) and archegonia (female). The gametes consist of flagellated sperm, which swim via water or are transported by insect species.

 It is called sporophyte because it undergoes asexual reproduction to produce spores. Production of spores involves meiosis, so that there is a return to the haploid condition. The haploid spores give rise to the gametophyte generation. One of the two generations is always more conspicuous and occupies a greater proportion of the life cycle. This generation is called as the dominant generation. In all Bryophytes the gametophyte generation is dominant. In all other land plants the sporophyte generation is dominant. It is customary to place the dominant generation in the top half of the life cycle diagram. The figure given above summarises the life cycle of a typical Bryophyte. One point that must be remembered here is that gamete production involves mitosis and not meiosis as in animals.

Tracheophytes are plants that contain vascular tissue; two of the major classes of tracheophytes are gymnosperms (conifers) and angiosperms (flowering plants). Tracheophytes, unlike bryophytes, have developed seeds that encase and protect their embryos. The dominant phase in the tracheophyte life cycle is the diploid (sporophyte) stage. The gametophytes are very small and cannot exist independent of the parent plant.

ADVERTISEMENTS: The life cycles of all sexually reproducing plants follow a pattern of alternation between a haploid, sexual generation called gametophyte with a diploid, asexual generation called sporophyte. This phenomenon of alternation between gametophyte (n) and sporophyte (2n) in the life cycle of a plant is called alternation of generations (Hofmeister, 1851). Alternation of generations is of two types- isomorphic and heteromorphy. In isomorphic (or homologous) type both the alternating generations are morphologically similar, while in heteromophic (or heterologous) type of alternation of generations both the generations of life cycle are morphologically dissimilar. ADVERTISEMENTS: In the life cycle, change of ploidy level from diploid (2n) to haploid (n) is brought about by meiosis and fertilization (syngamy) respectively. The sporophyte generation is “diploid” in which meiosis occurs to produce haploid spores, while gametophyte generation is “haploid” in which gametes are produced (by mitosis of haploid cells). In the life cycle, any one of the two generations is found to be always more conspicuous and survive a greater proportion is called as dominant generation. In algae and bryophytes the somatic or vegetative plant body is a gametophyte which is dominant and visible.

General Plant Life Cycle
Summary

The gametophyte has male or female reproductive organs that undergo mitosis to form haploid gametes (sperm or eggs). Fertilization of gametes produces a diploid zygote. The zygote grows and develops into a mature sporophyte, and the cycle repeats. This diagram represents the life cycle that generally characterizes plants. One of the two generations of a plant’s life cycle is typically dominant to the other generation. Whether it’s the sporophyte or gametophyte generation, individuals in the dominant generation live longer and grow larger. They are the green, photosynthetic structures that you would recognize as a fern, tree, or other plant (see Figure below ). Individuals in the nondominant generation, in contrast, may be very small and rarely seen. They may live in or on the dominant plant. The dominant generation in nonvascular plants is the gametophyte;

Which stage is the dominant stage in gymnosperms? Which stage is the dominant stage in gymnosperms?
Asked by: Yasir Tugujekov
Which stage is the dominant stage in gymnosperms?
 Gymnosperms, like all vascular plants, have a life cycle that is sporophyte-dominant. Also Know, in which group of plants is the Gametophyte the dominant stage? Thus, the gametophyte stage is dominant in the more primitive (nonvascular) plants (bryophytes), whereas the sporophyte is the dominant phase in the life cycle of higher (i.e., vascular) plants. In algae, the dominant phase often depends on environmental conditions, though some species have determinant life cycles. Consequently, what is the dominant stage in angiosperms? Angiosperms are vascular plants, and all vascular plants have a life cycle in which the sporophyte phase (vegetative body) is the dominant phase and the gametophyte phase remains diminutive. Which life stage in alternation of generations is dominant in gymnosperms and angiosperms plants with seeds )? In bryophytes, such as mosses and liverworts, the gametophyte is the dominant life phase, whereas in angiosperms and gymnosperms the sporophyte is dominant.

Solved Questions For You
 The gametophyte is the dominant phase. The diplontic life cycle is commonly seen in gymnosperms and angiosperms with some variations. However, an Alga called Fucus also shows this kind of life cycle. In a diplontic life cycle, the diploid sporophyte is dominant, photosynthetic and is the independent phase of the plant. The gametophyte stage is characterized by a single to a few-celled haploid gametophyte. Bryophytes and Pteridophytes show an intermediate condition called the haplo-diplontic life cycle, where phases are multicellular. But the dominant phase differs. In Bryophytes, the dominant phase is the gametophyte and in Pteridophytes, it is the sporophyte. Solved Questions For You

The life cycle of a dioicous bryophyte. The gametophyte (haploid) structures are shown in green, the sporophyte (diploid) in brown. Like all land plants (embryophytes), bryophytes have life cycles with alternation of generations. In each cycle, a haploid gametophyte, each of whose cells contains a fixed number of unpaired chromosomes, alternates with a diploid sporophyte, whose cell contain two sets of paired chromosomes. Gametophytes produce haploid sperm and eggs which fuse to form diploid zygotes that grow into sporophytes. Sporophytes produce haploid spores by meiosis, that grow into gametophytes. Bryophytes are gametophyte dominant, meaning that the more prominent, longer-lived plant is the haploid gametophyte. The diploid sporophytes appear only occasionally and remain attached to and nutritionally dependent on the gametophyte.

 Therefore, the life cycle of plants is known as alternation of generations. The ability of the plants to reproduce sexually and asexually helps them to adapt to different environments. The alternation of generations depends upon the type of the plant. In Bryophytes, the dominant generation is haploid and the gametophyte comprises the main plant. In tracheophytes, the dominant generation is diploid and the sporophyte comprises the main plant. The plants’ life cycle in one of the two generations is dominant over the other. The plants in the dominant generation grow larger and live longer. The plants in the non-dominant generations are small and hardly visible. On the contrary, the dominant generations are seen in the form of ferns, trees or other plants. The dominant generation in vascular plants is the sporophyte, while in the non-vascular plants is the gametophyte.

Also asked, which generation is dominant in Coniferophytes? Like the ferns and gymnosperms, angiosperms have a dominant sporophyte (2n) generation. Of the plants, angiosperms have the most dramatically reduced gametophytes with male (micro) gametophytes represented by a 3-celled structure and female (mega) gametophytes represented by a 7-celled structure. Secondly, why Sporophyte is dominant over Gametophyte? The union of two gametes during fertilization produces a diploid zygote, which divides mitotically to form a new sporophyte. Thus, in the higher (i.e., vascular) plants the sporophyte is the dominant phase in the life cycle, whereas in the more primitive nonvascular plants (bryophytes) the gametophyte remains dominant.

 In bryophytes, the gametophytic phase is a dominant phase and photosynthetic. Different Types of Life Cycle
There are three different types of life cycles found in kingdom Plantae. Haplontic Life Cycle
Here, the sporophytic phase is represented by a diploid zygote that undergoes meiosis to form haploid spores. The haploid spores then undergo mitosis to give rise to a new haploid gametophyte. In this cycle, the gametophytic phase is photosynthetic and dominant in nature. This life cycle is seen in some algae such as Volvox and Spirogyra. Diplontic Life Cycle
In this cycle, the gametophytic phase is a haploid gametophyte that can be single-celled or few-celled. Here the diploid sporophytic phase is photosynthetic, dominant and independent of the gametophyte. This kind of life cycle is found in an alga (Fucus), in all gymnosperms and angiosperms. Haplodiplontic Life Cycle
This is an intermediate between haplontic and diplontic life cycle.

 Emerging from the spore at the time of germination...
In the gametophyte phase, which is haploid (having a single set of chromosomes ), male and female organs (gametangia) develop and produce eggs and sperm ( gametes) through simple mitosis for sexual reproduction. When these unite in fertilization, the zygote then develops into the diploid (having two sets of chromosomes) sporophyte phase, which produces unicellular spores through meiosis. These, in turn, develop into a new gametophyte phase. moss life cycle

 Moreover, the sporophytes are dependent on the gametophyte for nutrition and develops within the female sex organ (archegonia). Bryophyte Life Cycle
The bryophyte lifecycle consists of alternating generations between the haploid gametophyte and the diploid sporophyte. During the gametophyte stage, haploid gametes (male and female) are formed in the specialized sex organs: the antheridia (male) and archegonia (female). The gametes consist of flagellated sperm, which swim via water or are transported by insect species. The two haploid gametes (sperm and egg) fuse, a diploid zygote is formed. As described above, the zygote of bryophytes grows inside the archegonia and will eventually become a diploid sporophyte. Mature sporophytes remain attached to the gametophyte and generate haploid spores via meiosis inside the sporangium. These spores are dispersed, and under favorable environmental conditions become new gametophytes. The lifecycle is shown below.

 It grows a tall stalk from the gametophyte. This stalk is often brown. A structure called the sporangium is at the top of the stalk. The sporangium is diploid too. It makes spores that are haploid in a process called meiosis. When the spores land on the ground, the cycle begins again. Life cycle of a dioicous bryophyte
Bryophytes are "gametophyte dominant." This phrase means when you look at a bryophyte, you are more likely to see the gametophyte. The sporophyte is less common. Sporophytes are always attached to the gametophyte.

Fertilization of gametes produces a diploid zygote. The zygote grows and develops into a mature sporophyte, and the cycle repeats. This diagram represents the life cycle that generally characterizes plants. One of the two generations of a plant’s life cycle is typically dominant to the other generation. Whether it’s the sporophyte or gametophyte generation, individuals in the dominant generation live longer and grow larger. They are the green, photosynthetic structures that you would recognize as a fern, tree, or other plant (see Figure below). Individuals in the nondominant generation, in contrast, may be very small and rarely seen. They may live in or on the dominant plant. The dominant generation in nonvascular plants is the gametophyte; in vascular plants, it’s the sporophyte.

General Plant Life Cycle
Summary
 The gametophyte has male or female reproductive organs that undergo mitosis to form haploid gametes (sperm or eggs). Fertilization of gametes produces a diploid zygote. The zygote grows and develops into a mature sporophyte, and the cycle repeats. This diagram represents the life cycle that generally characterizes plants. One of the two generations of a plant’s life cycle is typically dominant to the other generation.

 The spore mother cells undergo meiosis to produce haploid spores. Each spore produces a new gametophyte. Different members of plant kingdom have variation in their life cycle. In case of angiosperms and gymnosperms, the sporophyte plant body is a photosynthetic and dominant stage. In pteridophytes, the sporophytic phase is the dominant phase but is small and dependent on the gametophyte in the early stages. In bryophytes, the gametophytic phase is a dominant phase and photosynthetic. Different Types of Life Cycle
There are three different types of life cycles found in kingdom Plantae. Haplontic Life Cycle
Here, the sporophytic phase is represented by a diploid zygote that undergoes meiosis to form haploid spores. The haploid spores then undergo mitosis to give rise to a new haploid gametophyte. In this cycle, the gametophytic phase is photosynthetic and dominant in nature.

 In the species of rust fungi that attack ferns, part of the life cycle must be completed on the fern, and part on the fir tree. These parasitic fungi can usually be eradicated by simply eliminating one of the hosts, in this case, either the fern or the fir tree. Life cycle
Like all plants, the life cycle of ferns is characterized as having an alternation of a gametophyte phase and a sporophyte phase. A typical fern sporophyte is the large, familiar plant seen in nature. Its cells have the unreduced number of chromosomes, usually two sets. Most fern gametophytes are not seen in nature. A typical gametophyte is about 0.4 inches (1 cm) in diameter, multicellular, flat, heart-shaped, and green. Its cells have the reduced number of chromosomes, usually one set. Interestingly, the gametophyte and sporophyte are about equally dominant in the life cycle of ferns. In contrast, the gametophyte is dominant in the more evolutionarily primitive bryophytes (mosses, liverworts, and hornworts), whereas the sporophyte is dominant in the more evolutionarily advanced seed plants.

Though all plants display an alternation of generations life cycle, there are significant variations in different lineages of plants, consistent with their evolutionary history: In seedless non-vascular plants, or bryophytes (mosses), the haploid gametophyte is larger than the sporophyte (the plant structure that you see is the gametophyte); this is a gametophyte-dominated life cycle. The sporophyte is attached to and dependent on the gametophyte. ( By “dominated” we mean “the stage of the plant you can see by eye.”) In seedless vascular plants (ferns), the sporophyte is larger than the gametophyte (the plant structure that you see is the sporophyte), but the gametophyte is free-living and independent from the diploid sporophyte. The life cycle of angiosperms (flowering plants) and gymnosperms (conifers) is dominated by the sporophyte stage (the plant structure that you see is the sporophyte), with the gametophyte remaining attached to and dependent on the sporophyte (reverse of bryophytes).

The Life Cycle of Plants
All plants undergo a life cycle that takes them through both haploid and diploid generations. The multicellular diploid plant structure is called the sporophyte, which produces spores through meiotic (asexual) division. The multicellular haploid plant structure is called the gametophyte, which is formed from the spore and give rise to the haploid gametes. The fluctuation between these diploid and haploid stages that occurs in plants is called the alternation of generations. The way in which the alternation of generations occurs in plants depends on the type of plant. In bryophytes (mosses and liverworts), the dominant generation is haploid, so that the gametophyte comprises what we think of as the main plant. The opposite is true for tracheophytes (vascular plants), in which the diploid generation is dominant and the sporophyte comprises the main plant. Bryophyte Generations
Bryophytes are nonvascularized plants that are still dependent on a moist environment for survival (see Plant Classification, Bryophytes . Like all plants, the bryophyte life cycle goes through both haploid (gametophyte) and diploid (sporophyte) stages.

Are Anthophyta Gametophyte dominant? Of the plants, angiosperms have the most dramatically reduced gametophytes with male (micro) gametophytes represented by a 3-celled structure and female (mega) gametophytes represented by a 7-celled structure. Secondly, why Sporophyte is dominant over Gametophyte? The union of two gametes during fertilization produces a diploid zygote, which divides mitotically to form a new sporophyte. Thus, in the higher (i.e., vascular) plants the sporophyte is the dominant phase in the life cycle, whereas in the more primitive nonvascular plants (bryophytes) the gametophyte remains dominant. In this manner, which generation is dominant in Anthophytes? sporophyte
Are gymnosperms Gametophyte or Sporophyte dominant? Gymnosperms, like all vascular plants, have a sporophyte-dominant life cycle, which means they spend most of their life cycle with diploid cells, while the gametophyte (gamete-bearing phase) is relatively short-lived. Gametophytes, as with all heterosporous plants, develop within the spore wall.

Leave a Comment / Botany / By Supriya N
The life cycle of bryophytes has two alternations of generations, one is haploid gametophyte generation and the other is diploid saprophytic generation. In both the life cycle, the bryophytes possess different morphology and physiological functions. Between these two alternations of generation, the haploid gametophyte phase lasts longer or dominates the diploid saprophytic phase. Gametophytes (male and female gametes) are developed by the heterosporous (two types) bryophytes, where one kind of spore develops a male gametophyte, while the other develops a female gametophyte.

Meaning of Bryophytes
Bryophytes are the terrestrial, non-vascular plants that grow in damp or humid habitats and reproduce via spore generation instead from seed germination. Mosses, hornworts, and liverworts are the three common plants that come under the bryophyte group. There is one thing in common among the non vascular plants (mosses, liverworts and hornworts) that all possess small leaves, but lacks flowers, wood and true root system. In addition, the bryophytes possess dual generations (gametophytic and sporophytic phase) in their life cycle. Unlike vascular plants, bryophytes can survive in variety of habitats (rocks, roof , bare soil etc.)

 this is a gametophyte-dominated life cycle. The sporophyte is attached to and dependent on the gametophyte. ( By “dominated” we mean “the stage of the plant you can see by eye.”) In seedless vascular plants (ferns), the sporophyte is larger than the gametophyte (the plant structure that you see is the sporophyte), but the gametophyte is free-living and independent from the diploid sporophyte.

Though they both have sporophyte-dominated life cycles, angiosperms and gymnosperms differ in that angiosperms have flowers, fruit-covered seeds, and double fertilization, while gymnosperms do not have flowers, have “naked” seeds, and do not have double fertilization (more on this later).

Bryophytes can be found in almost all areas that are capable of supporting plant life in the Antarctic. Moss lawns often occur on meltwater flushes from ponds (such as at Casey station), or from glaciers (such as the Canada Glacier in Southern Victoria Land). Mosses have been collected from as far south as 84°30’ ( Ceratodon purpureus at Mt. Kyffin, Southern Victoria Land). Life Cycle
The dominant stage in the life cycle of bryophytes is the sexually reproducing gametophyte plant stage. But because of the extreme environmental conditions under which these plants exist, most reproduction occurs asexually. The plants can reproduce from a deciduous shoot apex or other specialised asexual reproductive structures, called gemmae. Sexual reproductive structures may be present on the gametophyte, but male and female organs are rarely found on the same plant. In many cases the sporophyte stage, produced after sexual reproduction, is completely absent amongst Antarctic bryophytes. This is more often true for the bryophytes of the Continental Antarctic, where only about 25% of moss species produce a sporophyte stage.

 All land plants, and most multicellular algae, have life cycles in which a multicellular diploid sporophyte phase alternates with a multicellular haploid gametophyte phase. In the seed plants, the largest groups of which are the gymnosperms and flowering plants (angiosperms), the sporophyte phase is more prominent than the gametophyte, and is the familiar green plant with its roots, stem, leaves and cones or flowers. In flowering plants the gametophytes are very reduced in size, and are represented by the germinated pollen and the embryo sac . The sporophyte produces spores (hence the name) by meiosis, a process also known as "reduction division" that reduces the number of chromosomes in each spore mother cell by half. The resulting meiospores develop into a gametophyte. Both the spores and the resulting gametophyte are haploid, meaning they only have one set of chromosomes. The mature gametophyte produces male or female gametes (or both) by mitosis. The fusion of male and female gametes produces a diploid zygote which develops into a new sporophyte. This cycle is known as alternation of generations or alternation of phases. In flowering plants, the sporophyte comprises the whole multicellular body except the pollen and embryo sac
Bryophytes ( mosses, liverworts and hornworts) have a dominant gametophyte phase on which the adult sporophyte is dependent for nutrition.

Q3. What Do You Mean by Sporophyte Generation?
 The alternation of generations depends upon the type of plant. The dominant generation is haploid and the gametophyte comprises the main plant in Bryophytes. In tracheophytes, the generation that dominates is diploid and the sporophyte has the main plant. The plants’ life cycle in one of the two generations is dominant over the other. The plants grow larger and live longer in the dominant generation whereas the plants in the non-dominant generations are small and hardly visible. On the other hand, the dominant generations are seen in the form of ferns, trees, or other plants. The dominant generation in vascular plants is the sporophyte, while in the non-vascular plants is the gametophyte. Alternation of Generations – Life Cycle
The alternation of generations include the following stages: The diploid sporophyte has a structure called a sporangium. The sporangium undergoes meiosis and forms haploid spores.

 This outline covers the easily recognised features of the ferns and their alies and mentions many of the technical terms used to describe them. Life cycle
The life cycle of pteridophytes involves two distinct and separate phases known as the gametophyte and sporophyte (these two phases also occur in the seed-plants, but because there they occur concurrently, they are less obvious). The sporophyte, is the most conspicuous phase, and is so-named because this is the stage that produces the spores; it is the sporophyte that most of us refer to when we describe or name a fern. Under favourable conditions, the spores shed from the sporophyte develop into the gametopyhte which is small, inconspicuous and short-lived. The purpose of the gametophyte is to produce the male and famale sex cells ( gametes ), the female of which, when fertilized, develops into a new sporophyte to continue the cycle. This regular process is known as the alternation of generations and involves an alternate doubling and halving of chromosome numbers at each phase. It is interesting to compare the pteridophyte life cycle with that of another major group of spore-producing plants, the bryophytes or mosses and liverworts which also have alternating generations. In the bryophytes, the gametophyte is the dominant and most conspicuous stage and the sporophyte is retained as a relatively small. dependent appendage on the mature gametophyte.

 In ferns, the sporophyte is the dominant generation, and it produces spores in sporangia that occur in clumps called sori that are found on the underside of the leaves. Spores grow into the gametophyte generation if they land in a suitable place. The gametes, eggs, and sperm are then formed by mitosis. Both the mosses and ferns are able to disperse by spores that are carried by the wind. The gametes, in both cases, also rely on the water so that the sperm can swim to the egg and fertilize it. The moss life cycle
Mosses are considered more primitive plants than ferns, but they do still have an alternation of generations with a diploid sporophyte that alternates with a haploid gametophyte. Mosses are in the Division Bryophyta and the gametophyte is the dominant stage of the life cycle. The morphology of a moss plant is a little different from that of more advanced plants. There are stem-like and leaf-like parts to the plant which is attached to the soil by a rhizoid which acts as a root. Together these structures form the gametophyte which is the haploid stage.

 Therefore, different generations are dominant in different plants. The following figure gives you an idea of the dominant and reduced stages in the life cycle of different plants. The haplontic life cycle is generally exhibited by algae. The sporophyte generation is represented only by a one-celled zygote. There are no free-living sporophytes. The gametophyte is the dominant phase. The diplontic life cycle is commonly seen in gymnosperms and angiosperms with some variations. However, an Alga called Fucus also shows this kind of life cycle. In a diplontic life cycle, the diploid sporophyte is dominant, photosynthetic and is the independent phase of the plant. The gametophyte stage is characterized by a single to a few-celled haploid gametophyte.

The Life Cycle Of A Plant: Conclusion
Main Points:
 When a male reproductive cell ( sperm) produced by a gametophyte fuses with a female reproductive cell ( egg) produced by a gametophyte of the same species, the result is a diploid cell called a zygote. This zygote develops and grows via mitosis into a sporophyte, thereby completing the plant’s life cycle. Moss (Leucolepis acanthoneuron) in its gametophyte phase (the dominant phase in the life cycle of bryophytes). One Generation Reduced In Size
In many plant groups, the members of one generation are reduced in size (often to just a few cells) and, rather than growing independently, develop inside the bodies of members of the other generation. For example, the gametophytes of angiosperms (flowering plants) and gymnosperms (plants such as conifers) are much reduced in size, comprising of just a few cells. In these plant groups, the male gametophyte is carried by pollen and develops within the stigma of a sporophyte, while the female gametophyte develops within the ovule (the egg-producing organ) of a sporophyte. The angiosperm and gymnosperm plants that we see around us are in their sporophyte phase. In bryophytes such as moss, the gametophyte stage is phase is the dominant phase. Self-Fertilization
Many species of plants produce individuals with both male and female parts. This can result in self-fertilization, which occurs when a plant’s sperm fertilizes its own eggs.

 Whether it’s the sporophyte or gametophyte generation, individuals in the dominant generation live longer and grow larger. They are the green, photosynthetic structures that you would recognize as a fern, tree, or other plant (see Figure below ). Individuals in the nondominant generation, in contrast, may be very small and rarely seen. They may live in or on the dominant plant. The dominant generation in nonvascular plants is the gametophyte; in vascular plants, it’s the sporophyte. Why is a dominant sporophyte generation an advantage on land? All of these photos show plants of the dominant generation in their life cycle. Life Cycle of Nonvascular Plants
Nonvascular plants include mosses, liverworts, and hornworts. They are the only plants with a life cycle in which the gametophyte generation is dominant.

In the species of rust fungi that attack ferns, part of the life cycle must be completed on the fern, and part on the fir tree. These parasitic fungi can usually be eradicated by simply eliminating one of the hosts, in this case, either the fern or the fir tree. Life cycle
Like all plants, the life cycle of ferns is characterized as having an alternation of a gametophyte phase and a sporophyte phase. A typical fern sporophyte is the large, familiar plant seen in nature. Its cells have the unreduced number of chromosomes, usually two sets. Most fern gametophytes are not seen in nature. A typical gametophyte is about 0.4 inches (1 cm) in diameter, multicellular, flat, heart-shaped, and green. Its cells have the reduced number of chromosomes, usually one set. Interestingly, the gametophyte and sporophyte are about equally dominant in the life cycle of ferns. In contrast, the gametophyte is dominant in the more evolutionarily primitive bryophytes (mosses, liverworts, and hornworts), whereas the sporophyte is dominant in the more evolutionarily advanced seed plants.

 The main plant body of bryophyte is gametophytic (n), which is independent and may be thallose (no differentiation in root, stem, leaves) e.g., Riccia, or may be foliose (having leafy axis) e.g., Funaria. The dominant phase in the life cycle of Funaria is the gametophyte, which occurs in two stages, the protonema stage and the erect, leafy gametophytic plant. The leafy gametophyte consists of an upright, slender axis (stem-like) that bears spirally arranged leaves and is attached to the substratum by multicellular, branched rhizoids. Vegetative reproduction takes place
by fragmentation; by the buds formed in secondary protonema etc. The sex organs, antheridia and archegonia are produced in dusters at the apices of the leafy shoots. Antheridia produces antherozoids and archegonia produces egg. Antherozoid (male gamete) and egg (female gamete) fuses and form zygote. Zygote develops into a sporophyte; which is differentiated into foot, seta and capsule and spores are produced in the capsule.

 Examples: Green algae, e.g. Volvox, Spirogyra, Chlamydomonas, etc. Diplontic Life Cycle – The diploid sporophyte is the dominant stage. It shows gametic meiosis. E.g. Gymnosperms, Angiosperms, Fucus, etc. Haplodiplontic Life Cycle – Here both haploid and diploid stages are multicellular. In some, the gametophyte is dominant and free-living and the sporophyte is a small and short-lived phase, which is dependent on gametophytes, e.g. Bryophytes. In pteridophytes, the sporophyte is the independent and free-living dominant stage. It alternates with short-lived gametophyte. Some algae such as Ulva, Polysiphonia, Ectocarpus, Kelps have a haplodiplontic life cycle.

 The term “bryophyte” comes from bryon “tree-moss, oyster-green” and phyton “plant”. The defining features of bryophytes are: Their life cycles are dominated by the gametophyte stage. Their sporophytes are unbranched. They do not have a true vascular tissue containing lignin (although some have specialized tissues for the transport of water). Bryophytes first appeared during the early Paleozoic. They can only survive where moisture is available for significant periods, although some species are desiccation-tolerant. Most species of bryophytes remain small throughout their life-cycle. This involves an alternation between two generations: a haploid stage, called the gametophyte, and a diploid stage, called the sporophyte.

 Moreover, the sporophytes are dependent on the gametophyte for nutrition and develops within the female sex organ (archegonia). Bryophyte Life Cycle
The bryophyte lifecycle consists of alternating generations between the haploid gametophyte and the diploid sporophyte. During the gametophyte stage, haploid gametes (male and female) are formed in the specialized sex organs: the antheridia (male) and archegonia (female). The gametes consist of flagellated sperm, which swim via water or are transported by insect species. The two haploid gametes (sperm and egg) fuse, a diploid zygote is formed. As described above, the zygote of bryophytes grows inside the archegonia and will eventually become a diploid sporophyte. Mature sporophytes remain attached to the gametophyte and generate haploid spores via meiosis inside the sporangium. These spores are dispersed, and under favorable environmental conditions become new gametophytes. The lifecycle is shown below.

Conclusion
 A spore capsule comprises a layer of sterile cells, second layer of elaters that are hygroscopic or absorbs moisture from the surrounding. The hydrogroscopic movement of the cells within the spore capsule results in flicking of the spores upward and outward. Unfortunately, the spore capsule ruptures, as the spores attain maturity and move freely in the environment as dormant spores. The life cycle of bryophyte continues once the dormant spore starts germinating into protonema. Conclusion
Therefore, we can conclude that the gametophyte phase contains haploid cells that possess an unpaired number of chromosomes. In contrast, the saprophyte phase includes diploid cells that possess two sets of paired chromosomes. Gametophyte phase occurs predominantly in all the bryophytes and lasts longer.

 The fusion of male and female gametes produces a diploid zygote which develops into a new sporophyte. This cycle is known as alternation of generations or alternation of phases. Bryophytes (mosses, liverworts and hornworts) have a dominant gametophyte phase on which the adult sporophyte is dependent for nutrition. The embryo sporophyte develops by cell division of the zygote within the female sex organ or archegonium, and in its early development is therefore nurtured by the gametophyte. Because this embryo-nurturing feature of the life cycle is common to all land plants they are known collectively as the embryophytes. Most algae have dominant gametophyte generations, but in some species the gametophytes and sporophytes are morphologically similar (isomorphic). An independent sporophyte is the dominant form in all clubmosses, horsetails, ferns, gymnosperms, and angiosperms that have survived to the present day. Early land plants had sporophytes that produced identical spores (isosporous or homosporous) but the ancestors of the gymnosperms evolved complex heterosporous life cycles in which the spores producing male and female gametophytes were of different sizes, the female megaspores tending to be larger, and fewer in number, than the male microspores. During the Devonian period several plant groups independently evolved heterospory and subsequently the habit of endospory, in which the gametophytes develop in miniaturized form inside the spore wall. By contrast in exosporous plants, including modern ferns, the gametophytes break the spore wall open on germination and develop outside it.

 The spores are therefore once again haploid and develop into haploid gametophytes. In bryophytes, the gametophyte is the dominant form and thus the most familiar phase of the life cycle. The sporophytes are typically attached to and dependent on the long-lived gametophytes. Moss gametophytes originate from the germination of a spore. The initial phase of growth leads to a filament of cells. The mature gametophyte of mosses produces the gamete-producing structures, archegonia and antheridia. In gametophyte dominant organisms, such as bryophytes, specialized structures or even whole individual plants that produce gametes are sometimes called gametophores. How to pronounce gametophyte?

When considering true ferns (Pteridophyta), similar to bryophytes, these ferns also show alternative generations. However, unlike bryophytes, ferns have a dominant sporophyte generation that is diploid. Gametophyte generation represents by a prothallus, which is green and photosynthetic produced by a spore of the sporophyte. The sporophyte is the diploid stage of the pteridophyte life cycle, and it is also photosynthetic. But, it does not produce flowers or seeds. Similar to bryophytes, ferns are also important plants. They act as soil binders. Also, they can use as ornamental plants.

H2O moves cell-to-cell by osmosis
Sphagnum moss is known for its moisture holding capacity, absorbing up to 20 times its dry weight with water. MOSS SPOROPHYTES & FERN GAMETOPHYTES
LIFE CYCLE OF MOSSES: Mosses alternate between a haploid (n) gametophyte stage & a diploid (2n) sporophyte stage
Gametophyte is the dominant generation

Called alternation of generations
The haploid gametophyte stage contains half the chromosome number & produces gametes (egg & sperm)
Gametophyte stage is dominant in the moss’s life cycle
Gametophytes are photosynthetic & have root-like rhizoids
The diploid sporophyte has a complete set of chromosomes & produces spores by meiosis
Sporophyte of a moss is smaller than, & attached to the Gametophyte
Sporophytes lack chlorophyll & depend on the photosynthetic gametophyte for food
Sporophyte has a long, slender stalk topped with a capsule
Capsule forms haploid (n) spores
Moss Capsules
Sexual Reproduction in Moss: Mosses produce 2 kinds of gametes (egg & sperm)
Gametes of Bryophytes are surrounded by a jacket of sterile cells that keep the cells from drying out
Female gametes or eggs are larger with more cytoplasm & are immobile
Flagellated sperm must swim to the egg through water droplets for fertilization
Moss gametes form in separate reproductive structures on the Gametophyte — Archegonium & Antheridium

Each Archegonium forms one egg, but each Antheridium forms many sperm
Fertilization can occur only after rain when the Gametophyte is covered with water
Sperms swim to the egg by following a chemical trail released by the egg
A zygote (fertilized egg) forms that undergoes mitosis and becomes a Sporophyte
Cells inside mature Sporophyte capsule undergoes meiosis and form haploid spores
Haploid spores germinate into juvenile plants called protonema
Protonema begin the Gametophyte generation
Protonema
Spores are carried by wind & sprout on moist soil forming a new Gametophyte
Asexual reproduction in Mosses: Asexual reproduction in moss may occur by fragmentation or gemmae
Pieces of a Gametophyte can break off & form new moss plants (fragmentation)
Gemmae are tiny, cup shaped structures on the Gametophytes
Raindrops separate gemmae from the parent plant so they can spread & form new Gametophytes

Uses for Moss: Help decomposer dead logs
Serve as pioneer plants on bare rock or ground

 They are the green, photosynthetic structures that you would recognize as a fern, tree, or other plant (see Figure below). Individuals in the nondominant generation, in contrast, may be very small and rarely seen. They may live in or on the dominant plant. The dominant generation in nonvascular plants is the gametophyte; in vascular plants, it’s the sporophyte. Why is a dominant sporophyte generation an advantage on land? All of these photos show plants of the dominant generation in their life cycle. Life Cycle of Nonvascular Plants
Nonvascular plants include mosses, liverworts, and hornworts. They are the only plants with a life cycle in which the gametophyte generation is dominant. Figure below shows the life cycle of moss.

Nonvascular plants include mosses, liverworts, and hornworts. They are the only plants with a life cycle in which the gametophyte generation is dominant. Figure below shows the life cycle of moss.

 The two stages are called the sporophyte generation and the
gametophyte generation. The life cycle of nonvascular plants includes an alternation of generations between a? diploid sporophyte and a haploid gametophyte
The most apparent trend involved the relative importance of the haploid gametophyte in contrast to the diploid sporophyte which became increasingly emphasized in the life cycle? Sporophyte :D
Diploid form in a plant's life cycle? The diploid form in a plant's life cycle is called the
sporophyte. Land plants have a complex life cycle that involves an
alternation of generations between a haploid gametophyte and a
diploid sporophyte. The generation of a tulip is the dominant phase of its life cycle? sporophyte generation

 The plant life cycle has mitosis occurring in
spores,
produced by meiosis, that germinate into the gametophytephase. Gametophyte size ranges from three cells (in pollen)
to several million (in a "lower plant" such as moss). Alternation
of generationsoccurs in plants, where the
sporophytephase is succeeded by the gametophyte phase. The sporophyte phase
produces spores by meiosis within a sporangium. The gametophyte phase produces gametes by mitosis within an
antheridium (producing sperm) and/or archegonium (producing eggs). Within the plant kingdom the dominance of phases varies. Nonvascular
plants, the mosses and liverworts, have
the gametophyte phase dominant. Vascular
plantsshow a progression of increasing
sporophyte dominance from the ferns and "fern allies" to
angiosperms. The above image is reduced from gopher://wiscinfo.wisc.edu:2070/I9/.image/.bot/.130/Angiosperm/Angiosperm_life_cycle. Follow that link to view a larger image.

 The sporophyte phase is "diploid", and is that part of the life cycle in which meiosis occurs. However, many plant species are thought to arise by polyploidy , and the use of "diploid" in the last sentence was meant to indicate that the greater number of chromosome sets occur in this phase. The gametophyte phase is "haploid", and is the part of the life cycle in which gametes are produced (by mitosis of haploid cells). In flowering plants ( angiosperms ) the multicelled visible plant (leaf, stem, etc.) is sporophyte, while pollen and ovaries contain the male and female gametophytes, respectively. Plant life cycles differ from animal ones by adding a phase (the haploid gametophyte) after meiosis and before the production of gametes. The above is from http://www.biosci.uga.edu/almanac/bio_104/notes/apr_3.html. Many protists and fungi have a haploid dominated life cycle. The dominant phase is haploid, while the diploid phase is only a few cells (often only the single celled zygote, as in Chlamydomonas ). Many protists reproduce by mitosis until their environment deteriorates, then they undergo sexual reproduction to produce a resting zygotic cyst.

The plants have a life cycle comprised of two generations, the gametophyte and the sporophyte. The gametophyte generation is the sexual phase of the plant life cycle. It starts at a haploid spore that undergoes mitosis to give rise to a haploid gametophyte that bears the sex organs. The sex organs, in turn, produce gametes that will participate later in fertilization. The union of male and female gametes gives rise to a diploid zygote that later develops into a sporophyte. The sporophyte generation is the phase in the plant life cycle that starts off with the zygote up to the time that spores are produced. The sporophyte produces spore s within the sporangium through meiosis. In tracheophytes (vascular plants), the sporophyte is the dominant form of the plant and is in the multicellular form. In contrast, the dominant form of the bryophytes, such as mosses and liverworts, is the gametophyte.

 LIVERWORTS: As you look at the materials of Marchantiadraw a chart that shows all the relevant structures superimposed on a diagram of the life cycle. Hand this chart in at the end of lab. Liverwort and moss life cycles are nearly identical. Marchantiathallus
Alternation of generations(sporophyte/gametophyte)
Like all plants, the bryophyte life cycle has an alternation of generations between a diploid sporophyte (2n) and a haploid gametophyte (n). In the bryophytes, unlike the other plants, the dominant, indeterminate generation is the gametophyte, whereas the sporophyte is determinate (once formed, there is no further development) and nutritionally dependant on the gametophyte. diploid sporophyte(2n) meiosis produces haploid spores(n)
haploid spores germinate (mitosis) into haploid thallus(n), the gametophyte, which can reproduce asexually by gemmae cupscontaining gemmaeor sexually with gametangiophores. fertilization of egg by sperm produces a diploid zygote(2n) which divides by mitosis into new sporophyte. The male gametangiophore is called an antheridiophore; it grows up from the thallus and consists of a stalk with a flat-topped head.

 Life Cycle and Reproduction
The bryophyte life cycle involves two distinct stages or an alternation of generations, each with a different physical form. These are the sporophyte and gametophyte generations. Each of these stages is named for what they produce. For example, the sporophyte generation produces the spores that develop into new plants. On the other hand, the gametophyte generation is the adult plant that produces the gametes, or haploid cells, that fuse together to form the viable spore. Spore Develops into the Gametophyte
First, a spore germinates to produce the protonema which is analogous to a seedling in a flowering plant. The small, threadlike protonema develops into the adult gametophyte stage which is characterized as the more elaborate, leafy stage of the plant’s life cycle. Gametophyte Releases Gametes
Depending on the plant, the gametophyte can produce male or female sex organs, with some species producing both. The female organ is called the archegonium and contains a single egg. The antheridium, or male organ, contains many cells that develop into sperm.

Alternation of Generations
Summary Alternation of Generations
All plants undergo a life cycle that takes them through both haploid and diploid generations. The multicellular diploid plant structure is called the sporophyte, which produces spores through meiotic (asexual) division. The multicellular haploid plant structure is called the gametophyte, which is formed from the spore and give rise to the haploid gametes. The fluctuation between these diploid and haploid stages that occurs in plants is called the alternation of generations. The way in which the alternation of generations occurs in plants depends on the type of plant. In bryophytes (mosses and liverworts), the dominant generation is haploid, so that the gametophyte comprises what we think of as the main plant. The opposite is true for tracheophytes (vascular plants), in which the diploid generation is dominant and the sporophyte comprises the main plant.

 Plants have complex lifecycles involving alternation of generations. One generation, the sporophyte, gives rise to the next generation asexually via spores. Spores may be identical isospores or come in different sizes (microspores and megaspores), but strictly speaking, spores and sporophytes are neither male nor female because they do not produce gametes. The alternate generation, the gametophyte, produces gametes, eggs and/or sperm. A gametophyte can be monoicous (bisexual), producing both eggs and sperm or dioicous (unisexual), either female (producing eggs) or male (producing sperm). In the bryophytes ( liverworts, mosses and hornworts ), the sexual gametophyte is the dominant generation. In ferns and seed plants (including cycads, conifers, flowering plants, etc.) the sporophyte is the dominant generation. The obvious visible plant, whether a small herb or a large tree, is the sporophyte, and the gametophyte is very small. In seed plants, each female gametophyte, and the spore that gives rise to it, is hidden within the sporophyte and is entirely dependent on it for nutrition.

FAQ (Frequently Asked Questions)
Q1. What is the Alternation of Generations?
Q2. Mention the Steps Involved in the Alternation of Generations
Q3. What Do You Mean by Sporophyte Generation?
 Alternation of generations is a common factor in plants, algae, and fungi. This can be compared to the sexual reproduction in animals where both haploid and diploid cells are found in every generation. Plants alternate between the diploid sporophyte and haploid gametophyte, and between asexual and sexual reproduction. Because of this reason, the life cycle of plants is termed as an Alternation of Generations. The ability of the plants to reproduce sexually and asexually helps them to adapt to different environments. The alternation of generations depends upon the type of plant. The dominant generation is haploid and the gametophyte comprises the main plant in Bryophytes. In tracheophytes, the generation that dominates is diploid and the sporophyte has the main plant. The plants’ life cycle in one of the two generations is dominant over the other. The plants grow larger and live longer in the dominant generation whereas the plants in the non-dominant generations are small and hardly visible.

Therefore, the life cycle of plants is known as alternation of generations. The ability of the plants to reproduce sexually and asexually helps them to adapt to different environments. The alternation of generations depends upon the type of the plant. In Bryophytes, the dominant generation is haploid and the gametophyte comprises the main plant. In tracheophytes, the dominant generation is diploid and the sporophyte comprises the main plant. The plants’ life cycle in one of the two generations is dominant over the other. The plants in the dominant generation grow larger and live longer. The plants in the non-dominant generations are small and hardly visible. On the contrary, the dominant generations are seen in the form of ferns, trees or other plants. The dominant generation in vascular plants is the sporophyte, while in the non-vascular plants is the gametophyte.
