Ch 26: GRE Biology: Plant Reproduction, Growth, and Development

About This Chapter

Watch these short, informative video lessons to review plant reproduction, growth and development. The lessons and the quizzes that follow are designed to prepare you to answer related questions on the GRE Biology Test.

GRE Biology: Plant Reproduction, Growth, and Development - Chapter Summary

Learn all you need to know about the life and growth cycles of plants by watching these video lessons taught by experts in the field of biology. The lessons offer a fun and effective way for you to study this topic as you get ready for the GRE Biology test. Lessons in this chapter cover:

  • Moss life cycle
  • Fern life cycle
  • Asexual plant reproduction
  • Seasonal growth cycles of perennial, annual and biennial plants
  • Plant hormones
  • Flowering plant reproduction
  • Phototropic, geotropic and thigmotropic plant growth

Watch these brief lessons as many times as you need or use the jump feature in the timeline to review main points. Transcripts of each lesson are available to reinforce the information taught in the videos. Then, take the chapter exam to test your retention of plant reproduction, growth and development covered in the lessons.

GRE Biology Objectives

The GRE Biology Test is an achievement test for applicants to demonstrate to graduate school admissions committees the breadth of their knowledge of biology. The test consists of 190 multiple-choice questions and is organized into three main subject areas: cellular and molecular biology, organismal biology, and ecology and evolution. Plant reproduction, growth and development questions are included under the organismal biology subject area and make up 5% of the total number of questions on the test. The GRE Biology Test is provided in a paper format and offered three times per year.

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.

How a Plant Body Develops

11. How a Plant Body Develops

View this lesson to learn how plants develop. Discover the terms that describe how a plant goes from seed to full-grown plant. Learn what goes on at the cellular level as the plant grows.
