About This Chapter
Basic Plant Physiology - Chapter Summary
What is osmosis? What happens during transpiration in plants? How do plants obtain nutrition? These are examples of the types of facts you will learn more about in these lessons, which cover everything from cellular respiration to water transportation in plants. Review term definitions and various processes by which plants feed, stay hydrated and produce energy. Once you have successfully completed this chapter, you should possess the following abilities:
- Explain different ways in which substances are moved from cell to cell in a plant
- Detail systems that move water and nutrients through plants
- Define water potential and give information about how it is calculated
- Summarize how osmosis works
- Discuss the transpiration process in plants
- Relate the steps in the nitrogen cycle
- Provide details about two types of agricultural nutrition: autotrophic and heterotrophic
- Identify the stages of aerobic cellular respiration
- List the steps in cellular respiration in plants and explain the process of photosynthesis
Lessons use illustrations, definitions and easy-to-follow language to present the material in an engaging and fun manner. These lessons are accessible at any time, on any device, and can be printed for easy reference. Take self-assessment quizzes to measure the depth of your knowledge and determine the need for further review, and send questions about any topic directly to instructors. Your Dashboard is a great tool for tracking your progress through this chapter.
1. Plant Tissue Compartments & Transport
This lesson goes over three ways substances like water and solutes can be transported from cell to cell in a plant: the symplastic, apoplastic, and transmembrane routes.
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. How Solutes and Pressure Affect Water Potential in Plants
Plants are great at using and moving water. In this lesson, we'll explore the concept of water potential as it applies to plants and check out how solutes and pressure can both impact the total water potential within an organic system.
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. Osmosis: Definition & Examples
Water moves across cell membranes by osmosis to try to equalize the concentration of solutes on both sides of the membrane. In this lesson, learn how osmosis works and examine some examples of its importance in biology.
6. 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.
7. The Nitrogen Cycle: Definition, Facts & Steps
Oh the places we'll go on our nitrogen cycle tour! Nitrogen is an element that cycles through you, me, plants, and other organisms. This lesson will not only follow nitrogen on this cycle, but will also share some nitrogen facts!
8. Nutrition: Autotrophic & Heterotrophic
In this lesson, we'll review the difference between autotrophs and heterotrophs and explain different modes of nutrition in heterotrophs. We'll also look at how modes of nutrition impact food web efficiency, and thus commercial agriculture.
9. Aerobic Cellular Respiration: Stages, Equation & Products
Aerobic cellular respiration is the process in which our cells break down food and turn it into energy that cells need to perform their life functions. This lesson goes through the process, formula, and end results of aerobic cellular respiration.
10. Cellular Respiration in Plants
In this lesson, we'll learn what cellular respiration is and the role it has in plants. We'll cover what is used and made in cellular respiration and why plants need it.
11. Glycolysis and Cellular Respiration
In this lesson, we will review cellular respiration and explore a distinct, important part of its process: glycolysis. We will also cover the role of enzymes, ATP, and oxygen in glycolysis.
