When the sun shines, a leaf becomes a food factory. Sunlight comes into a leaf through the leaf’s skin, which is clear like glass. Beneath the skin are millions of tiny ‘bags’ called cells. Inside the cells are small packages filled with a green stuff called chlorophyll. The chlorophyll catches sunlight.

Air comes into the leaf through many tiny openings. Water and minerals, moving up from the roots far below; flow through the leaf. The air and water mix together and flow into the cells.

Green chlorophyll, using sunlight for energy, changes water and a gas from the air (called carbon dioxide) into sugar. Some of this sugar is used by the plant as food. Some is mixed with minerals from the ground and changed into other kinds of food.
