Ch 7: Overview of Photosynthesis

About This Chapter

Get a better understanding of photosynthesis with these lessons on chlorophyll, root hairs, stomata of plants, and more. These fun lessons and printable quizzes are easy to use and can help you prepare for an exam or simply ensure that you truly comprehend the topics covered.

Overview of Photosynthesis - Chapter Summary

During the process of going through these lessons, you can improve your knowledge of photosynthesis. This interactive chapter includes a review of how chlorophyll is used by plants. There are also discussions covering the importance of xylem and phloem. After reviewing the lessons, you should be ready to:

  • Describe how plants harness light energy from the sun to feed us
  • Explain how photosynthesis works
  • Recall how human organisms use energy in sugar to perform work
  • Detail the function and structure of stomata of plants
  • Communicate how water moves up a plant
  • Explain how sugars move throughout vascular plants
  • Discuss the function of root hairs in plants

These lessons can assist you with quickly getting up to speed on photosynthesis. Key words are highlighted in bold, which makes it easy for you to reference and review important concepts. Each lesson includes a full written transcript that you can print and use as a study guide.

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.

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!

Energy and Life: The Transformation of Energy in Living Organisms

3. 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.

Stomata of Plants: Function, Definition & Structure

4. Stomata of Plants: Function, Definition & Structure

Did you know that plants 'breathe' through their leaves? Tiny openings called stomata allow plants to exchange gases necessary for cellular processes, such as photosynthesis.

Xylem: The Effect of Transpiration and Cohesion on Function

5. Xylem: The Effect of Transpiration and Cohesion on Function

Roots absorb water and leaves release water, but how does water move up a plant? In this lesson, we will look at how this happens in vascular plants, including the importance of xylem, cohesion and transpiration in the process.

Phloem: The Pressure Flow Hypothesis of Food Movement

6. Phloem: The Pressure Flow Hypothesis of Food Movement

Leaves produce sugars and stems; roots and fruits use these sugars for energy. In this lesson, we will look at how these sugars move throughout vascular plants, including the importance of phloem and the pressure flow hypothesis in the process.

Root Hairs in Plants: Function & Definition

7. Root Hairs in Plants: Function & Definition

In this lesson, you will learn about root hairs, which are the structures that allow a plant to get water and nutrients from the soil. They are a delicate but necessary component of a plant's overall root system.
