Cause and Effect — From Sunlight to Growth
Plants get sunlight and water
↓
Leaves make food
Chlorophyll, carbon dioxide, and water make glucose.
↓
Food and water move
Xylem carries water up; phloem carries food everywhere.
↓
Respiration releases energy
Glucose breaks down using oxygen to give energy.

10.1
How Plants Grow
Plants need both sunlight and water to grow.
10.2
Getting Food
Leaves make food; chlorophyll catches sunlight.
10.2.3
Photosynthesis
Carbon dioxide and water make glucose and oxygen.
10.2.4
Stomata
Tiny leaf pores exchange gases.
10.3
Transport
Xylem carries water; phloem carries food.
10.4
Respiration
Glucose breaks down to release energy.
Key Terms and Definitions

- Food Factory
- The leaf, where a plant prepares its food.
- Iodine Test
- A test that turns blue-black to show starch is present.
- Carbon Dioxide
- The gas from air that plants use to make food.
- Photosynthesis
- Making food using sunlight, chlorophyll, carbon dioxide, and water.
- Glucose
- A simple carbohydrate made during photosynthesis.
- Oxygen
- The gas released by plants during photosynthesis.
- Stomata
- Tiny pores on leaves that help exchange gases.
- Minerals
- Important nutrients in the soil needed for growth.
- Xylem
- The tube that carries water and minerals up the plant.
