What Plants Need to Grow

Plants help many things grow—including us!

What do plants need to grow?

Air

Humans need air to breathe. But plants need air too! Plants take carbon dioxide out of the air. The plants use the carbon dioxide to make sugars and starches that the plant uses as food.

Light

Plants use energy from sunlight to help them make sugars and starches. These sugars and starches are used by the plant to grow and be healthy.

Water

Have you ever seen a plant that wilted? It probably needed water. Like humans, plants need water to grow and be healthy.

Plant Challenge!

How much air, light, and water is needed for plants to grow? How could you test this out?

carbon

Carbon Dioxide

Carbon dioxide is a gas that is found in the air and in the ocean. When there is too much of it, it is bad for humans. But carbon dioxide is good for plants. Plants take it in and turn it into oxygen. Oxygen is good for humans. Plants and people work together!
