Ch 60: Photosynthesis, Transpiration & Respiration

About This Chapter

Examine the lessons in this chapter to learn more about the processes of respiration, transpiration and photosynthesis. You can use these lessons as test prep, to help boost your grades, or to expand your personal knowledge for your own enrichment.

Photosynthesis, Transpiration & Respiration - Chapter Summary

There's considerably more excitement involved in watching plants grow than you might expect. In these lessons, you'll study the processes, products and reactants involved in photosynthesis, transpiration, and anaerobic and aerobic respiration. You will learn about the Calvin-Benson cycle, photolysis and the light reaction, and how chlorophyll absorbs light energy. Upon completion, you should know how to:

  • Discuss the role of chlorophyll in photosynthesis
  • Define and explain the light and dark cycles
  • Explain carbon fixation in photosynthesis
  • Describe the processes involved in transpiration and respiration
  • Compare and contrast anaerobic and aerobic respiration

This study guide's readily-accessible, user-friendly online platform allows you to study whenever you like. You can work in any location and from any Internet-capable device. Short, yet informative and interesting video and text lessons provide comprehensive instruction while helping you to use your time to your best advantage. Lesson quizzes and a chapter exam let you check for comprehension and retention, and our expert instructors and subject-matter specialists are available for assistance if you need help.

Chlorophyll: Absorbing Light Energy for Photosynthesis

1. Chlorophyll: Absorbing Light Energy for Photosynthesis

Plants are clean, green, photosynthesizing machines. Using a specialized pigment called chlorophyll, plants are able to soak up energy from the sun and turn it into food. In this lesson, we'll start to learn why chlorophyll literally gets excited about a sunny day!

Photolysis and the Light Reactions: Definitions, Steps, Reactants & Products

2. Photolysis and the Light Reactions: Definitions, Steps, Reactants & Products

In this lesson, we'll learn how electrons get excited during the light-dependent reactions of photosynthesis, jumping off photosystem reaction centers like they were trampolines! In addition, we'll learn how the splitting of water creates reactants for this part of photosynthesis while creating a little fresh air for us.

Dark Reactions of Photosynthesis: The Calvin-Benson Cycle

3. Dark Reactions of Photosynthesis: The Calvin-Benson Cycle

Photosynthesis starts out using the energy from sunlight to get things started, but it ends with the dark reactions, which don't need sunshine to complete sugar production. In the Calvin cycle, ATP and NADPH from the light reactions are used to produce sugars.

Carbon Fixation in Photosynthesis: Definition & Reactions

4. 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.

What Is Transpiration in Plants? - Definition, Rate & 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.

Anaerobic Respiration: Definition, Equation & Examples

6. Anaerobic Respiration: Definition, Equation & Examples

Many organisms are capable of undergoing anaerobic respiration. In some cases, it's a 'backup plan' when oxygen is absent, and in other cases, they thrive that way. Here we will investigate what anaerobic respiration is, the equation and examples of it at work.

Aerobic Respiration: Definition, Steps, Products & Equation

7. Aerobic Respiration: Definition, Steps, Products & Equation

Aerobic respiration is the process most living things undergo to use food energy. Here, we will investigate the definition, the steps of the process, what goes in and what comes out of the process, and the chemical formula. Get ready to breathe!

Plant Respiration: Definition & Process

8. 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.
