| Question | Answer |
|---|---|
| What are some ancestral characteristics of land plants that are shared with the chlorophytes and other green plants? | 1. Chrolorophylls A & B in photosynthesis with starch as storage product. Cellulose in cell walls. 2. Plasmodesmata joining the cytoplasm of adjacent cells 3. Branching, apical (tip) growth 4. Retention of the egg in the parent organism |
| What are ten groups (clades) of land plants (seven of these are grouped together in the vascular plants)? | 1. Hepatophyta 2. Anthocerophyta 3. Bryphyta 4. Lycophyta 5. Pteridophyta 6. Cycadophyta 7. Ginkgophyta 8. Gnetophyta 9. Coniferophyta 10. Angiosperms |
| What are some synapomorphies (shared, derived characters) of land plants? Describe each. | Embryophytes, |
| Describe the general life cycle of land plants including the stages of alternation of generations. | |
| What are the major trends found in plant evolution seen in the seedless plants through the seedless, vascular plants? What evolutionary advantages do these provide? | |
| Describe the life cycle of bryophytes. Include the different structure involved in reproduction. | |
| What are synapomorphies of vascular plants? Describe them. | |
| Describe the different groups of the nonvascular and seedless vascular plants, and know their taxonomic and common names. Give examples. | |
| Describe the life cycle of ferns, including the major reproductive structures involved. How does this life cycle differ from that of mosses? | |
