About This Chapter
Plant Structures & Reproduction - Chapter Summary
Work through this chapter on plant structures and reproduction to explore leaf structures, plant fertilization, plant growth, flower components and more. You'll learn from expert science instructors who craft each lesson to be simple, straightforward and fun. You can reinforce your understanding by taking the accompanying self-assessment quizzes and chapter exam. We've made the chapter accessible on any Internet-connected device, which allows you to study at home, at school or when you're on the go. By the end of the chapter, you should be able to:
- Outline the structure of leaves
- Evaluate the function of roots and stems
- Differentiate between the male and female flower components
- Understand how flowering plants reproduce and fertilize
- Compare phototropic, geotropic and thigmotropic plant growth
1. Structure of Leaves: The Epidermis, Palisade and Spongy Layers
Leaves may look pretty in the fall when they are changing colors, but they also provide many necessary functions for plants. In this lesson, we will explore the structures and functions of leaves.
2. Roots & Stems: Structure & Function
You have probably pulled a plant out of the ground by its stalk (stem) to reveal the jumbled mess of roots below, but do you know how roots and stems help a plant stay alive? Learn what is inside roots and stems and what they do.
3. Flowers: Structure and Function of Male & Female Components
In this lesson, we'll look at the parts of a flower and learn their functions. These natural beauties provide indispensable services to the plants they adorn.
4. Flowering Plants: Reproduction & Fertilization
Some plants use flowers to reproduce. The flowers contain all the parts needed for the reproduction process. This lesson explains how all of these parts are used to create the next generation of flowering plants.
5. 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.
