About This Chapter
Photosynthesis Fundamentals - Chapter Summary
This self-paced biology chapter examines the fundamentals of photosynthesis through short and expertly taught lessons. Take a look through the chapter to study the process of photosynthesis, the absorption of light energy, dark reactions, the functions of chlorophyll and much more. Following each lesson is a short quiz to help you solidify your understanding of the information and commit essential photosynthesis terms to memory. Take the chapter exam to make sure you fully understand these biology concepts, and don't hesitate to use the Ask the Expert feature if you have any questions. Upon completion of the chapter, you should be able to:
- Describe energy and matter changes during the photosynthesis process
- Evaluate photosynthesis' balanced chemical equation
- Outline the structure of the chloroplast
- Explain how chlorophyll absorbs light energy for photosynthesis
- Recognize the reactants and products of photolysis and light reactions
- Analyze the Calvin-Benson cycle
1. Matter & Energy Changes During Photosynthesis
Photosynthesis is how plants make food. Like all processes, it involves inputs and outputs of matter and energy. Learn about those flows of matter and energy, and what they teach us about the universe.
2. Balanced Chemical Equation for Photosynthesis
This lesson will go over the basics of photosynthesis and its chemical reaction, explaining how the chemical equation is formed and how it can be balanced.
3. Chloroplast Structure: Chlorophyll, Stroma, Thylakoid, and Grana
In this lesson, we'll explore the parts of the chloroplast, such as the thylakoids and stroma, that make a chloroplast the perfect place for conducting photosynthesis in plant cells.
4. 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!
5. 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.
6. 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.
