Passage 1: Photosynthesis is how plants make their own food in their leaves. Plants need sunlight, water, and carbon dioxide from the air. This process is important because it helps plants grow strong. It also supports many food chains on Earth.

Passage 2: During photosynthesis, chlorophyll in leaves captures sunlight energy. The plant uses that energy to turn water and carbon dioxide into sugar. Oxygen is made too, and it is released into the air. Animals and people use this oxygen to breathe.

Read both passages and combine information from each to explain why photosynthesis matters to living things.

Read Passage 1 and Passage 2.

Passage 1: Plants have tiny openings in their leaves called stomata. Stomata let carbon dioxide enter the leaf from the air. Plants also move water from their roots up to their leaves. These materials are needed to make food.

Passage 2: In photosynthesis, chlorophyll captures sunlight and powers a chemical change. Water and carbon dioxide are turned into sugar for the plant. Oxygen is produced and released into the air. This happens mostly in the leaves.

Using information from both passages, why are leaves important to photosynthesis?
