During the gametophyte stage of bryophytes

WebJan 13, 2024 · Figure 1. Alternation of generation life cycle pattern of land plants. Lower plants ( Bryophyta) spend the majority of their life in the gametophyte stage, whereas the sporophyte stage is the dominant stage in vascular plants (gymnosperms and angiosperms). Fertilization and meiosis function as ontogeny switch points. WebThe completion of the bryophyte and pterophyte life cycle requires water because the male gametophyte releases sperm, which must swim—propelled by their flagella—to reach and fertilize the female gamete or egg. After fertilization, the zygote matures and grows into a sporophyte, which in turn will form sporangia or “spore vessels.”

WebJun 7, 2024 · During the mature gametophyte stage, several mosses including, Sphagnum recurvum, Sphagnum cuspidatum, and Sphagnum palustre, bear large central vacuoles in thick walled sterome cells, while the internal thin-walled cells possess abundant number of small vacuoles ( Ligrone and Duckett, 1998 ). WebRegular heteromorphic alternation of generation occurs in bryophytes. The gametophyte produces haploid gametes. After fertilization the oospore gives rise to diplopod sporophyte. The sporophyte produces the spores by meiosis. The spores give rise to the gametophyte.
