Chapter 10 ยท CBSE Class 7 Biology (NCERT Curiosity)

Life Processes in Plants

Learn how plants make food through photosynthesis, transport water and nutrients, and exchange gases through their leaves.

๐ŸŒฟ Chapter 10

10.1

Photosynthesis

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to produce food (glucose) and release oxygen.

1

What raw materials does a plant need for photosynthesis?

Sunlight, water, and carbon dioxide

2

What does a plant produce through photosynthesis?

Glucose (food) and oxygen

10.2

Transport and Gas Exchange in Plants

Plants transport water and minerals from roots to leaves, and exchange gases like oxygen and carbon dioxide through tiny pores called stomata.

1

What are the tiny pores on a leaf's surface called?

Stomata

2

What do plant roots absorb from the soil?

Water and minerals

Practice

Exercises

1. What are the raw materials for photosynthesis?

2. What gas do plants release during photosynthesis?

3. What are the tiny pores on a leaf called?

4. What do plant roots absorb from the soil?

5. Why is photosynthesis important for other living things, not just the plant?
