Absorption & Movement of Water in Plants - Chapter Summary
Study the basics of absorption and movement of water in plants with help from the expert instruction in this chapter. Engaging lessons help you gain full comprehension of plant translocation, root pressure, guttation and more. Once you've completed this chapter, you will be ready to:
- Explain how water and solutes are transported in plants
- Define turgor pressure in plants
- Differentiate between plasmolysis and deplasmolysis
- Describe passive and active absorption of water in plants
- Discuss the rate and process of transpiration in plants
- Share details about the function of stomata of plants
- Exhibit knowledge of osmosis and diffusion
Align your review of this chapter with your personal schedule and unique study needs. Select any number of lessons to view, and navigate them in any sequence you desire. Short quizzes enable you to test your knowledge of the lessons you explore. To ensure you fully understand absorption and movement of water in plants, take this chapter's comprehensive practice exam.
1. Plant Translocation: Definition & Mechanism
When plants create nutrients in their leaves, how do materials get to the rest of the plant? In this lesson, you'll learn about the movement mechanism known as plant translocation.
2. Transporting Solutes & Water in Plants
How do plants move water and nutrients where they need to go? That's the question we'll be exploring in this lesson as we look at both xylem and phloem transportation systems and see how plants stay hydrated and energized.
3. Turgor Pressure in Plants: Definition & Overview
In this lesson, you will learn about the structure of plant cells and how the pressure inside is crucial for the plant's ability to grow and stand tall.
4. What are Plasmolysis & Deplasmolysis?
In this lesson, you'll learn what happens during plasmolysis and deplasmolysis and their relationship to water balance in plants. You'll also learn where these processes occur in everyday life.
5. Passive & Active Absorption of Water in Plants
All living organisms need some amount of water. In this lesson, we'll look at both passive and active absorption of water in plants to see how they take place and how water moves once inside the cells.
6. Root Pressure: Definition & Theory
This lesson defines root pressure and its effect on plants. It also looks to the extent that root pressure has been scientifically proven, and how alternative theories come into play.
7. What Is Transpiration in Plants? - Definition, Rate & Process
Did you know that plants 'sweat?' Transpiration is both an important and costly process for plants, and it requires that a delicate balance between it and other necessary cellular processes be maintained.
8. Stomata of Plants: Function, Definition & Structure
Did you know that plants 'breathe' through their leaves? Tiny openings called stomata allow plants to exchange gases necessary for cellular processes, such as photosynthesis.
9. Guttation: Definition & Mechanism
What exactly is guttation? How does it happen and how is it different from transpiration? If you are curious about these questions and want to get to the root of this process, read on.
10. Diffusion and Osmosis: Biology Lab
Molecules are always on the move thanks to kinetic energy. This energy makes diffusion and osmosis possible, two processes used by cells to maintain homeostasis. In this lab, we'll look how osmosis and diffusion work and what factors affect them.
11. Transpiration: Biology Lab
Transpiration, movement of water from the roots to shoots of a plant, is crucial to a plant's ability to maintain homeostasis. This lab examines both the mechanism of transpiration and the effects of the environment on this important process.
