Ch 26: Praxis Biology & General Science: Plant Reproduction & Growth

About This Chapter

Let us teach you about plant reproduction and growth. The video lessons and self-assessment quizzes in this chapter can help you correctly answer questions about diversity of life, plants and animals on the Praxis II Biology and General Science test.

Plant Reproduction & Growth - Chapter Summary

Explore seasonal growth cycles of plants through this online chapter on plant reproduction and growth. This is one of several chapters that can help you prepare for the Praxis II: Biology and General Science test. Other topics covered in this series of brief video lessons include the gymnosperm and angiosperm life cycles, as well as asexual plant reproduction via vegetative propagation or bulbs. Additional areas of study include the following:

  • Alternation of generations: The gametophyte and sporophyte
  • The moss life cycle: Dominant gametophyte
  • The fern life cycle: Plant reproduction without flowers or seeds
  • Tropisms: Phototropic, geotropic and thigmotropic plant growth
  • Photoperiodicity: Short-day, long-day and day-neutral plants
  • Plant hormones: Chemical control of growth and reproduction

Plant Reproduction & Growth Objectives

A number of states use Praxis II tests, including the biology and general science test, as part of their certification process for public high school teachers. The biology and general science test features 120 multiple-choice questions. Approximately 17% of these questions focus on diversity of life, plants and animals; this section is likely to include questions on plant reproduction and growth. You'll have two hours to finish the test.

To help you prepare for the Praxis II: Biology and General Science exam, our team of professional educators crafted these lessons on plant reproduction and growth. Learning tools included in this chapter include several comprehensive video presentations, most of which are just 5-10 minutes in length, along with written transcripts and short multiple-choice quizzes.

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.

Tropisms: Phototropic, Geotropic and Thigmotropic Plant Growth

7. Tropisms: Phototropic, Geotropic and Thigmotropic Plant Growth

Animals aren't the only things that can respond to the environment. While plants may seem inanimate at times, they, too, can respond to the environment in order to better survive.

Photoperiodicity: Short-day, Long-day and Day-Neutral Plants

8. Photoperiodicity: Short-day, Long-day and Day-Neutral Plants

Ever wonder why some plants will bloom in the spring but others in the summer? The length of daylight can influence when a flower will bloom. We will look at how the amount of sunlight regulates when plants produce flowers.

Seasonal Growth Cycles: Perennial, Annual and Biennial Plants

9. Seasonal Growth Cycles: Perennial, Annual and Biennial Plants

We continue to grow and change throughout our entire lives, living through many seasons and years. Plants have different patterns of growth and development regarding seasons, which we will look at in this lesson.

Plant Hormones: Chemical Control of Growth and Reproduction

10. 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.
