About This Chapter
Understanding Plant Biology - Chapter Summary
Plants are busy structures, performing various functions ranging from photosynthesis to water absorption. In this chapter, you can review details about how plants pull water from the ground, transport nutrients, perform cellular processes and maintain energy production. After completing your study of this chapter, you should be able to do the following:
- Define the process of capillary action in plants
- Describe the theory of root pressure
- Explain how plants stay hydrated and energized
- Detail the phases of plant respiration
- Discuss transpiration in plants
- Provide details about carbon fixation in the photosynthesis process
- Identify alternative energy production solutions adopted by plants
These detailed topics are explained in simple language and use illustrations and examples to clarify information. Lessons are accessible from any device at any time, making it easy to study when it's convenient for you. Track your progress through this chapter on your Dashboard and take self-assessment quizzes for each lesson to help confirm your readiness in moving from one topic to the next.
1. Capillary Action in Plants: Definition & Examples
Capillary action is the process that plants use to pull water up from the ground. This lesson explains what capillary action is, describes all the forces necessary for it to happen, and goes through examples of the process.
2. 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.
3. 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.
4. Plant Respiration: Definition & Process
Cellular respiration is essential to the survival of all plants and animals. In this lesson, we'll look at what plant respiration is, why it is important, and the three main phases involved in the process.
5. 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.
6. Carbon Fixation in Photosynthesis: Definition & Reactions
In this lesson, you will discover what carbon fixation means, when it occurs and what enzyme is involved. The lesson will discuss where the process of carbon fixation falls in photosynthesis as well as give a brief idea of a process by which carbon can be freed from fixation.
7. Alternative Methods of Carbon Fixation in Plants
What happens to plants when it gets too hot or dry for the normal cycles of creating energy to keep functioning? In this lesson, we are going to check out a couple alternative solutions adapted by plants to maintain energy production when the need arises.
