The roots of a plant are spread out. Raises the height of flowers and leaves. Brings closer to light. The stem is made up of little tubes. Almost always green but sometimes covered with another colour such as red.
Leaves make food for the plant.
To do this they need the water and mineral salts obtained from the soil. They are carried inside little veins in the leaf. To make food leaves also need sunshine and CO2. Space and warmth also needed for a plant to grow. They take the water and mineral salts and use them together with sunlight and carbon-dioxide to make food.
