Ch 28: How Plants Grow & Reproduce - Middle School Life Science: Homeschool Curriculum

About This Chapter

The How Plants Grow and Reproduce unit of this Middle School Life Science Homeschool course is designed to help homeschooled students learn about the growth cycle of plants. Parents can use the short videos to introduce topics, break up lessons and keep students engaged.

Who's it for?

This unit of our Middle School Life Science Homeschool course will benefit any student who is trying to learn about plant growth cycles. There is no faster or easier way to learn how plants grow and reproduce. Among those who would benefit are:

  • Students who require an efficient, self-paced course of study to learn about tropisms, growth cycles, chemical control, fern life cycle and plant hormones.
  • Homeschool parents looking to spend less time preparing lessons and more time teaching.
  • Homeschool parents who need a life science curriculum that appeals to multiple learning types (visual or auditory).
  • Gifted students and students with learning differences.

How it works:

  • Students watch a short, fun video lesson that covers a specific unit topic.
  • Students and parents can refer to the video transcripts to reinforce learning.
  • Short quizzes and a How Plants Grow and Reproduce unit exam confirm understanding or identify any topics that require review.

How Plants Grow and Reproduce Unit Objectives:

  • Understand the relationship between gametophytes and sporophytes.
  • Get an overview of the moss life cycle.
  • Examine what occurs during the fern life cycle, which doesn't include seeds or flowers.
  • Learn about plant reproduction with 'naked seeds'.
  • Discover how flowering plants are reproduced.
  • Explore tropisms and how they relate to plant growth.
  • Compare photoperiodicity among plants.
  • Study the growth cycle for plants.
  • Analyze hormone levels of plants and how they affect 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.

Tropisms: Phototropic, Geotropic and Thigmotropic Plant Growth

6. 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

7. 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

8. 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

9. 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.
