The fern life cycle and moss life cycle are similar in that they have alternation between sporophyte and gametophyte stages and that both rely on layers of water so that their sperm can swim from one...
Life cycle of a Bryophyte (moss). The moss sporophyte depends on the gametophyte and is not a freeâliving independent plant. The spores form after meiosis and germinate to develop into male or female gametophytes.Moss sperm are produced from cells in the antheridia of the male gametophyte.The moss eggs are located at the base of the archegonia, on the female gametophyte. Each sperm has two flagella. Sperm swim to the eggs and after fertilization, the zygote develops into the sporophyte.oss sperm are produced from cells in the antheridia of the male gametophyte.
