WebBryophytes Three phyla: hepatophyta (liverworts), anthocerophyta (hornworts), and bryophyta (mosses); nonvascular plants. Form persistent, photosynthetic gametophytes and small, unbranched sporophytes; grow in environments where ability to pull water from soil has no advantage. Three classes: peat mosses, granite mosses, true mosses. sterile jacket 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.”
