2. Alternation of Generations

3. MulticellularGametangia A feature distinguishing early land plants from their algal ancestors was the production of gametes in multicellular organs called gametangia. The female gametangia are called archegonia, and the male gametangia are called antheridia. Antheridia release sperm, and archegonia each harbor a single egg.

4. Types of Plants Bryophytes: Nonvascular plants. Gametophytes dominant stage in life cycle. Constrained on height due to absence of vascular tissue. Angiosperms: Seed plants that produce the reproductive structures known as flowers and fruits. Vascular tissue allows for high growth, and flowers are specialized for sexual reproduction. Animals are used to pollinate flowers, and fruit are used for dispersal of offspring. Gymnosperms: Angiosperms whose seeds are not enclosed in chambers. Naked seed plants.
