About This Chapter
Plant Absorption & Transpiration - Chapter Summary
The lessons in this chapter provide an overview of plant absorption and transpiration. For example, you will learn what happens during plasmolysis and deplasmolysis. You will also come to understand the importance of xylem and phloem. After completing the chapter, you should be prepared to:
- Explain why root hairs are important to the plant's overall root system
- Discuss water absorption and movement in plants
- Provide a definition for turgor pressure in plants
- Describe passive and active absorption of water in plants
- Explain why transpiration is a costly process in plants
- Recall the function of plant stomata
- Differentiate guttation from transpiration in plants
- Describe how transpiration is examined in a biology lab
You can study all the lessons in order, or just the topics you need to review. Our instructors provide plenty of helpful illustrations to help you comprehend mechanisms used by plants to absorb water. A brief quiz is available for each lesson to test your knowledge, and you can print the quizzes for use as a study tool.
1. Root Hairs in Plants: Function & Definition
In this lesson, you will learn about root hairs, which are the structures that allow a plant to get water and nutrients from the soil. They are a delicate but necessary component of a plant's overall root system.
2. Water Absorption & Movement in Plants
In this lesson, you will learn about the complex process involved in the transport and absorption of water from the roots to the leaves of different types of plants.
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. Xylem: The Effect of Transpiration and Cohesion on Function
Roots absorb water and leaves release water, but how does water move up a plant? In this lesson, we will look at how this happens in vascular plants, including the importance of xylem, cohesion and transpiration in the process.
7. Phloem: The Pressure Flow Hypothesis of Food Movement
Leaves produce sugars and stems; roots and fruits use these sugars for energy. In this lesson, we will look at how these sugars move throughout vascular plants, including the importance of phloem and the pressure flow hypothesis in the process.
8. 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.
9. 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.
10. 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.
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.
