Ch 8: Prentice Hall Biology Chapter 8: Photosynthesis

About This Chapter

The Photosynthesis chapter of this Prentice Hall Biology Textbook Companion Course helps students learn the essential biology lessons of light and dark reactions in photosynthesis. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the photosynthesis textbook chapter.

How it works:

  • Identify the lessons in Prentice Hall Biology's Photosynthesis chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the photosynthesis topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, re-watch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • The transformation of energy in living organisms
  • The role of chlorophyll in photosynthesis
  • Steps, reactants and products of photolysis
  • Steps and products of the Calvin-Benson cycle

Energy and Life: The Transformation of Energy in Living Organisms

1. Energy and Life: The Transformation of Energy in Living Organisms

While the sun is an excellent source of energy, not all forms of life can utilize the sun's energy directly. This lesson describes how plants transform the sun's energy into potential energy stored in sugar, how living organisms utilize energy in sugar to perform work, and how the relationship between photosynthesis and cellular respiration is necessary for life.

Chlorophyll: Absorbing Light Energy for Photosynthesis

2. 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

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.
