How Plants Make Their Food

Plants are amazing. They can make their own food using sunlight, water and carbon dioxide. This process is called photosynthesis. In a plant, the leaves are the main food factories. They are green because they contain a chemical called chlorophyll. Chlorophyll captures sunlight.

The roots of a plant absorb water and minerals from the soil. The water travels up the stem to the leaves. At the same time, carbon dioxide enters the leaves through tiny openings. With the help of sunlight, the leaves combine water and carbon dioxide to produce sugar. This sugar is the plant's food. It provides energy for the plant's growth.

During this process, plants also produce oxygen. They release oxygen into the air. This is very important for animals and humans because they need oxygen to breathe. In fact, plants are the main source of oxygen on Earth.

Plants also store the sugar they produce. Some of it is used for growth, while the rest is stored in roots, fruits or seeds. That is why fruits taste sweet. So when you eat an apple or a carrot, you are actually eating the plant's stored food.

( )1. Where does photosynthesis mainly happen?
A. In the roots. B. In the stems. C. In the leaves. D. In the flowers.

( )2. What does chlorophyll do?
A. It absorbs water. B. It captures sunlight.
C. It produces oxygen. D. It stores sugar.

( )3. What do plants produce during photosynthesis?
