About This Chapter
Who's it for?
This unit of our AP Biology Homeschool course will benefit any student who is trying to learn about the life cycle of plants. There is no faster or easier way to learn about plant reproduction and growth. Among those who would benefit are:
- Students who require an efficient, self-paced course of study to learn about types of plant reproduction, plant hormones, seasonal growth cycles and photoperiodicity.
- Homeschool parents looking to spend less time preparing lessons and more time teaching.
- Homeschool parents who need a biology 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 plant reproduction and growth unit exam confirm understanding or identify any topics that require review.
Plant Reproduction & Growth Unit Objectives:
- Examine what occurs in plants during alternation of generations.
- Explore the life cycle stages of mosses.
- Learn about ferns' life cycle and how they reproduce without seeds.
- Discover how gymnosperms reproduce with 'naked' or unprotected seeds.
- Understand flowering plant reproduction and the life cycle of angiosperms.
- Identify forms of asexual reproduction in plants.
- Review the types of tropism in plants.
- Learn about photoperiodism and how the amount of sunlight affects plants' flowering.
- Distinguish between the seasonal growth cycles of annuals, perennials, and biennials.
- Discover the role of hormones in plant reproduction and growth.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
