Plants are made up of many parts. Three of the most important are their roots, stems, and leaves. All three of them have various functions.
The roots are found at the bottom of the plant. Roots grow underground. They help anchor the plant to the ground. This keeps the plant from being washed away by rain or blown away by the wind. Also, a plant's roots help it extract nutrients from the ground. These nutrients include water and various minerals.
The stems have several important responsibilities. First, they move water and nutrients from the roots to the leaves. They also store some nutrients and water if the plant has too much of them. And they transport food, such as sap, down from the leaves to the roots. Finally, they provide support for the leaves.
The leaves have a very important role. They contain chloroplasts. These let photosynthesis take place. Because of this, plants can create sugar, which they use for food. And they also take carbon dioxide and turn it into oxygen. This lets all of the other animals on Earth breathe.
