Ch 9: Plant Photosynthesis Processes

About This Chapter

These lessons on the processes of plant photosynthesis can assist you with a homework assignment, class project, or test preparation. You can review chloroplast structure, dark reactions of photosynthesis, and other photosynthesis topics from a platform that works on either a computer or your mobile device.

Plant Photosynthesis Processes - Chapter Summary

This chapter on plant photosynthesis discusses processes such as photolysis and light reactions. You'll review the steps and reactants for these and other photosynthesis processes and learn how to set up a photosynthesis lab experiment. You can also learn about the role and function of chloroplasts in cells. After completing the chapter, you should be able to:

  • Explain how plants use light energy from the sun
  • Discuss where chloroplasts are found
  • Describe the light-dependent reactions of photosynthesis
  • Recall the steps of the Calvin-Benson cycle
  • Conduct an experiment that measures the rate of photosynthesis

These lessons feature a clear instruction style and plenty of examples to make the material easy to understand. A full written transcript accompanies each video, in case you are partial to text-based learning. If you find yourself struggling with a topic, you can use the Help feature to submit questions to instructors. A brief quiz is available for each lesson to test your knowledge.

Photosynthesis: Definition & Reactions

1. Photosynthesis: Definition & Reactions

Some people may falsely assume plants to be weaker than animals. However, plants and a few other organisms harness light energy from the sun to feed the rest of us. This lesson will introduce you to how they do it.

Chloroplast: Definition, Structure, Function & Examples

2. Chloroplast: Definition, Structure, Function & Examples

A chloroplast is a basic organelle that in a sense is one of the most important organelles to us, and we don't even have them! In this lesson, we will be looking where chloroplasts are found and what their role and function is in cells.

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

3. 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

4. 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.

Photosynthesis: Biology Lab

5. Photosynthesis: Biology Lab

Plants and other organisms that have the pigment chlorophyll can do something that no other living creature can - capture light energy from the sun and use it to make chemical energy through photosynthesis. In this lab, we'll see how we can set up an experiment to measure the rate of this important process.
