This process is called photosynthesis.
Water and mineral salts travel from the roots through the stem to the leaves.
In the leaves, the water and mineral salts mix with carbon dioxide and become food for the plant.
To carry out photosynthesis, plants need to use a lot of energy from sunlight.
During photosynthesis, plants release oxygen.
All the oxygen in the air comes from photosynthesis.
