Nonvascular Plants Are Diverse
The nonvascular plants, which include the liverworts and mosses, are nonvascular plants and therefore lack true roots, stems, and leaves. In the moss life cycle, the gametophyte is dominant. Antheridia produce swimming sperm that need external water to reach the eggs in the archegonia. Following fertilization, the dependent sporophyte consists of a foot, a stalk, and a capsule within which wind-
blown spores are produced by meiosis. Each spore germinates to produce a gametophyte.
