CHAPTER 29
1. Define and distinguish between the sporophyte and gametophyte stages of a plant life cycle.
2. Explain why seedless vascular plants are commonly found in damp habitats.
3. Explain how vascular plants differ from bryophytes.
4. Explain why most bryophytes grow close to the ground.
CHAPTER 30
5. Define fruit, and explain why a cereal grain is a fruit rather than a seed.
6. Name the six angiosperms that are most important in the diet of the human species.
CHAPTER 35
7. Explain this statement: “In contrast to most animals, which have a stage of embryonic growth, plants have regions of embryonic growth.”
8. Contrast primary growth of the tissues of roots and shoots with secondary growth of the tissues of roots and shoots.
9. Distinguish between determinate and indeterminate growth. Give an example of each type of growth.
10. Distinguish between annual, biennial, and perennial plants.
CHAPTER 36
11. Explain the benefits and costs of the broad external surface area of many leaves.
12. Explain how the physical properties of plant cells are changed when the plant is placed into solutions that have higher, lower, or the same solute concentration.
13. Explain how transpirational pull moves xylem sap up from the root tips to the leaves.
14. Explain this statement: “The ascent of xylem sap is ultimately solar powered.”
15. Explain why crassulacean acid metabolism (CAM) is an important adaptation to reduce transpiration in arid environments.
