OAE - Biology: Plant Reproduction & Growth - Chapter Summary
These simple, enjoyable video lessons help you study plant reproduction and development by covering key concepts in an easy-to-understand way. When you're done studying this chapter, you should be able to:
- Understand why plants alternate between gametophytes and sporophytes
- Track the life cycles of ferns and mosses
- Describe naked seeds and explain their place in a gymnosperm's life cycle
- Explain the flowering plant reproduction of an angiosperm
- Define asexual plant reproduction
- Differentiate between phototropic, geotropic and thigmotropic plant growth
- Describe how plants react to photoperiodicity
- Chart the seasonal growth cycles of perennial, annual and biennial plants
- Discuss how plant hormones drive a plant's growth and reproduction
Our instructors are experts at taking complicated information like the growth and reproduction cycles of plants and making them seem way less daunting. Watch each video lesson as many times as you like, and then head on over to our self-assessment quizzes to try out some practice questions.
OAE - Biology: Plant Reproduction & Growth - Chapter Objectives
For teaching candidates in Ohio, the Ohio Assessments for Educators (OAE) is a requirement. Teachers need to pass the OAE exam corresponding to the concentration they plan on teaching. Secondary school life sciences teachers must score a 220 on the OAE Biology exam in order to pass.
The OAE Biology exam consists of five domains, each focused on a different aspect of biology. The biological unity and diversity domain, which covers 20% of the 150 multiple-choice questions on the exam, includes questions about plant reproduction and growth. You will have three hours to complete the entire exam.
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.
