Plant Diversity II
Chapter 30  - Campbell and Reece - 8th Ed.

1. Describe the major reproductive adaptations observed in the seed-bearing plants (reduced gametophytes, dispersed pollen, retained female gametophyte, seeds).   What is the adaptive significance of each?

2. Describe the structural and reproductive structures of the gymnosperms (D. Coniferophyta (conifers), D. Cycadophyta, D. Ginkophyta, D. Gnetophyta).  Outline the development of the male and female gametophytes in gymnosperms.

3. How did the changing environmental conditions near the end of the Paleozoic promote the diversification of gymnosperms.

4. What reproductive advantages are found only in the angiosperms (D. Anthophyta)?  What is their adaptive significance?

5. Diagram the structure of a typical flower.  What are common functions of each part?

6. Outline the development of the male and female gametophyte in angiosperms.  How does the development of the gametophyte generation differ from that of  gymnosperms?

7. Define coevolution in the context of the plant kingdom.

8. What is the difference between pollination and fertilization?  What is meant by double fertilization?  Which groups of plants exhibit double fertilization?

10. What was the impact of the development of the plant kingdom on atmospheric carbon dioxide?  How did this change during the Carboniferous period?

11. What are some advantages of  maintaining the diversity of the plant kingdom?
