Best Answer

Plants use a process called photosynthesis in order to change sunlight into food.

This process takes place mostly in the leaves of a plant. Leaves are large and flattened so that a large area of chlorophyll is exposed to the sunlight.

Leaves are also used in a process called transpiration, which helps draw water and dissolved minerals up the plant's stem from the roots, where these substances have been absorbed from the soil.

During transpiration, water evaporates through tiny holes in the leaves. More water is drawn up through a thin tube extending down the plant's stem.
