Ch 20: Plant Growth and Reproduction

About This Chapter

This chapter provides you with a way to reinforce your understanding of plant life cycles, propagation, reproduction, and more. These lessons are a great way to help with your biology homework or study for a test. They can also be used by casual learners who wish to learn more about plant growth and reproduction.

Plant Growth and Reproduction - Chapter Summary

To some, plant reproduction may seem like a strange concept, but plants go through hormonal and reproductive cycles just as animals do, albeit in a different manner. Our professional instructors assembled these lessons to help students, like yourself, reinforce their understanding of this subject. With this chapter you will review information about plant life cycles, reproduction and hormones. These lessons can help you to:

  • Define gametophytes and sporophytes
  • Explain reproduction and life cycles of seedless pants
  • Discuss the life cycles of plants with 'naked seeds'
  • Examine angiosperm life cycles
  • Relate asexual plant reproduction
  • Discover how plant hormones regulate growth and reproduction

7 Lessons in Chapter 20: Plant Growth and Reproduction
Alternation of Generations: The Gametophyte and Sporophyte

1. Alternation of Generations: The Gametophyte and Sporophyte

Even though many plants seem simple, they often have very complex life cycles. We will look at how plants alternate between different life stages as well as the terms used to describe these unique points in their life cycle.

A Moss Life Cycle: Dominant Gametophyte

2. A Moss Life Cycle: Dominant Gametophyte

Mosses are unique because they spend most of their lives with only one set of genetic material rather than the normal two sets. We will look at this cycle and how the alternation of generations takes place in these non-vascular plants.

A Fern Life Cycle: Plant Reproduction Without Flowers or Seeds

3. A Fern Life Cycle: Plant Reproduction Without Flowers or Seeds

Ferns are able to reproduce without using seeds. We will look at how ferns reproduce as well as the pattern of alternating between diploid and haploid life stages.

A Gymnosperm Life Cycle: Reproduction of Plants with 'Naked Seeds'

4. A Gymnosperm Life Cycle: Reproduction of Plants with 'Naked Seeds'

Some plants, such as pine trees, are able to reproduce with unprotected seeds. We will look at the major structures involved in this form of alternation of generations in gymnosperms.

An Angiosperm Life Cycle: Flowering Plant Reproduction

5. An Angiosperm Life Cycle: Flowering Plant Reproduction

When you think of how plants reproduce, you probably think of flowers. We will look at how flowering plants use specialized reproductive structures to complete an alternation of generations life cycle.

Asexual Plant Reproduction: Vegetative Propagation and Bulbs

6. Asexual Plant Reproduction: Vegetative Propagation and Bulbs

Not all plants make attractive flowers in order to reproduce. Some plants will not make seeds and pollen either. These plants have other ways to create new offspring. We will look at a few key methods of vegetative propagation.

Plant Hormones: Chemical Control of Growth and Reproduction

7. Plant Hormones: Chemical Control of Growth and Reproduction

We most often think of hormones as things that control our actions and development. However, even plants have these chemicals to help regulate growth and reproduction.
