Reproduction in Nonvascular Plants ï Nonvascular plants have a life cycle called alternation of generations. â¢ A gamete-producing stage (gametophyte) alternates with a spore-producing stage (sporophyte).â¢ Gametophytes produce gametes (eggs and sperm) in separate multicellular structures.eproductive Structures of Seed Plants ï Reproduction in seed plants (gymnosperms and angiosperms) is very different from reproduction in seedless plants. ï You need a microscope to see the gametophytes of seed plants. ï Spores are not released from seed plants.
The spores of seed plants, however, are produced internally and the megaspores, formed within the ovules and the microspores are involved in the formation of more complex structures that form the dispersal units, the seeds and pollen grains.eterosporous plants, such as seed plants, spikemosses, quillworts, and some aquatic ferns produce spores of two different sizes: the larger spore (megaspore) in effect functioning as a female spore and the smaller (microspore) functioning as a male.
