Sexual Reproduction |
1. | In general terms, explain how the basic plant life cycle with alternation of generations is modified in angiosperms. |
2. | List four floral parts in order from outside to inside a flower. |
3. | From a diagram of an idealized flower, correctly label the following structures and describe the function of each structure: a. sepals b. petals c. stamen (filament and anther) d. carpel (style, ovary, ovule, and stigma) |
4. | Distinguish between: a. complete and incomplete flowers b. bisexual and unisexual flowers c. monoecious and dioecious plant species |
5. | Explain by which generation, structure, and process spores are produced. |
6. | Explain by which generation, structure, and process gametes are produced. |
7. | Name the structures that represent the male and female gametophytes of flowering plants. |
8. | Describe the development of an embryo sac and explain the fate of each of its cells. |
9. | Explain how pollen can be transferred between flowers. |
10. | Distinguish between pollination and fertilization. |
11. | Describe mechanisms that prevent self-pollination. |
12. | Outline the process of double fertilization. Explain the adaptive advantage of double fertilization in angiosperms. |
13. | Explain how fertilization in animals is similar to that in plants. |
14. | Describe the fate of the ovule and ovary after double fertilization. Note where major nutrients are stored as the embryo develops. |
15. | Describe the development and function of the endosperm. Distinguish between liquid endosperm and solid endosperm. |
16. | Describe the development of a plant embryo from the first mitotic division to the embryonic plant with rudimentary organs. |
17. | From a diagram, identify the following structures of a seed and state a function for each: a. seed coat b. proembryo c. suspensor d. hypocotyls e. radicle f. epicotyl g. plumule h. endosperm i. cotyledons j. shoot apex |
18. | Explain how a monocot and dicot seed differ. |
19. | Explain how fruit forms and ripens. |
20. | Distinguish among simple, aggregate, and multiple fruit. Give an example of each type of fruit. |
21. | Explain how selective breeding by humans has changed fruits. |
22. | Explain how seed dormancy can be advantageous to a plant. Describe some conditions for breaking dormancy. |
23. | Describe the process of germination in a garden bean. |
| |
| Asexual Reproduction |
24. | Describe the natural mechanisms of vegetative reproduction in plants, including fragmentation and apomixis. |
25. | Explain the advantages and disadvantages of reproducing sexually and asexually. |
26. | Explain various methods that horticulturalists use to propagate plants from cuttings. |
27. | Explain how the technique of plant tissue culture can be used to clone and genetically engineer plants. |
28. | Describe the process of protoplast fusion and its potential agricultural impact. |
| |
| Plant Biotechnology |
29. | Compare traditional plant-breeding techniques and genetic engineering, noting similarities and differences. |
