Red and green algae are the closest relatives to land plants. 2. Caulerpa can be an invasive green alga Chapter 29 PLANT DIVERSITY I: HOW PLANTS COLONIZED LAND 1. Land plants evolved from green algae. 2. Some key traits of land plants are present in protists. 3. Charophytes are the closest algal relative to plants. 4. Adaptations required for transmission to land. 5. The 4 derived traits of land plants. 6. First plants were non-vascular plants termed bryophytes. 7. Life cycle of bryophytes dominated by gametophytes. 8. Bryophyte sperm require water to swim to eggs. 9. Seedless vascular plants were first tall plants. 10. Transport in xylem and phloem allowed plants to grow tall. Chapter 30 PLANT DIVERSITY II: THE EVOLUTION OF SEED PLANTS 1. Seeds and pollen grains facilitated adaptation to terrestrial life – freeing plants from being close to water. 2. Life cycle of seed plants is dominated by sporophytes. 3.
