Students will review:
This chapter helps students review the concepts in a plant reproduction and growth unit of a standard high school biology course. Topics covered include:
- Asexual and sexual plant reproduction
- Plant hormones
- Seasonal growth cycles
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.
11. What Is Phototropism? - Definition, Experiments & Examples
Why do plants bend toward sunlight? Phototropism is one way a plant can maximize its exposure to sunlight, and because plants need sunlight to make food, this is an important survival tactic.
12. Geotropism: Definition, Examples & Experiments
In this lesson, you'll learn about geotropism, which is why some parts of plants grow upward, while other parts grow toward the ground. Then, test your knowledge with a quiz.
13. How Seeds Germinate: Definition & Explanation
Plants function on a rather complex level when compared to other organisms. One of the ways plants reproduce is through seeds. Those seeds must germinate to grow into plants. We will look at the process of seed germination here.
14. Plant Fertilization: Process & Definition
For you, pollen might just be a trigger for sneezing and watery eyes. But for plants, it's a vital ingredient in the reproductive process. Explore plant fertilization through this lesson; then, test your knowledge of what you've learned.
15. Plant Tubers: Types & Examples
It is a good idea to store supplies for difficult times. Did you know plants can do this too? In this lesson, we will examine the different types of tubers and how plants use them.
