Reproduction in Plants

Alternation of generations in flowering plants, embryo development, fruit and seeds, and asexual propagation of plants are topics covered in this chapter.

Chapter 34 Outline

In this chapter outline, the learning objectives and the selected key terms are given for each major head in the chapter.

Flowering Plants Undergo Alternation of Generations (p. 586)

1. Draw and explain a diagram that shows the life cycle of flowering

plants.

2. State and describe the parts of a flower.

3. Describe the development of a megagametophyte in flowering plants from

the megasporocyte to the production of an egg.

4. Describe the development of the microgametophyte in flowering plants from

the microsporocyte to the production of sperm.

5. Distinguish between pollination and fertilization, and explain the events of

double fertilization in flowering plants.

Selected Key Terms: microspore, megaspore, flower, sepal, petal, pistil, carpel,

stigma, style, ovary, ovule, stamen, anther, filament, megasporocyte,

megagametophyte, embryo sac, microsporocyte, pollen grain,

microgametophyte, pollination, fertilization, embryo, endosperm

The Embryo Develops in Stages (p. 593)

6. Describe the development of a dicot embryo in terms of a sequence of

stages.

The Seeds Are Enclosed by Fruit (p. 595)

7. Give a classification of fruits, and list examples of different types of fruits.

8. Describe different means of dispersing seeds and fruits.

9. Contrast the structure and the germination of a bean seed with those of a corn

kernel.

seed, fruit, germinate, plumule
