Nutrients and water travel from the stems to the leaves. The leaves then use the water and nutrients along with sunlight to make sugar. The sugar is sent to other parts of the plant. The process in which plants make food is called photosynthesis. In photosynthesis, the leaves use carbon dioxide from the air, nutrients, water, sunlight, and a substance called chlorophyll to make sugar, which moves to other parts of the plant like stems, root, flowers, and fruits. The process of photosynthesis releases oxygen into the air.

Entry 12: In your Agronaut Log, draw a diagram that shows the relationship between people and plants.

Leaves can come in many different shapes and sizes. They are designed to catch light and have many openings called stomata that let air and water come and go. You can only see stomata using a microscope. Leaves are covered with a waxy coating called a cuticle that protects them.
