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.

To clarify, ‘terrestrial’ means they grow on land, and nonvascular refers to their lack of food and water-conducting channels. …
