1. 22-2 Bryophytes Chapter 22 Plant Diversity

2. Bryophyte Nonvascular plant; examples are mosses and their relatives.

3. Rhizoid In fungi, a rootlikehypha that penetrates the surface of an object; in mosses, a long, thin cell that anchors the moss to the ground and absorbs water and mineral from the surrounding soil.

4. Gemma (singular) Small cup-shaped structure in liverworts that contains many haploid cells; used for asexual reproduction.

5. Protonema Mass of tangled green filaments in mosses that forms during germination.

6. Antheridium Male reproductive structure in some algae and plants.

7. Archegonium Female reproductive structure in some plants, including mosses and liverworts.

8. Key Concept Bryophytes have life cycles that depend on water for reproduction. Lacking vascular tissue, these plants can draw up water by osmosis only a few centimeters above the ground.

9. Key Concept Bryophytes include mosses, liverworts, and hornworts.

10. Key Concept In bryophytes, the gametophyte is the dominant, recognizable stage of the life cycle and is the stage that carries out most of the plant’s photosynthesis.
