WebTypes of sexual life cycles. Sexual life cycles involve an alternation between meiosis and fertilization. Meiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells (gametes) fuse to form a diploid zygote. What happens between these two events, however, can differ a lot between different organisms ...

Bryophytes are gametophyte dominant, [10] 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.

WebThe sporophyte refers to the diploid generation of the moss. It remains attached to the gametophyte (the haploid mother), and is in fact, parasitic upon it. The sporophyte relies on the gametophyte to provide it with food and water, which are passed through transfer cells that lie in the placental layer between the gametophyte and the sporophyte.

WebHere are two young sporophytes (Spor) which develop into the “ferns” you see in the forest. You can see the gametophyte (Gam) still attached at the base of the fronds. Haploid spores are produced on the fern sporophyte by meiosis and eventually germinate into new gametophytes, completing the life cycle.
