Answer:
Plants, just like people, need food to survive.
Plants, however, can’t just run down to the shop and get the ingredients for a nice sandwich for their lunch! So, they have to make their own kind of food.
Plants make their food in a process called photosynthesis. What a big word! It actually means “making things using light”, photo meaning light, and synthesis meaning “to make”.
Plants need three main ingredients to make their food: water, carbon dioxide and sunlight. Plants take up the water that they need from the soil through their roots. Carbon dioxide is a gas found in the air; plants can take in this gas through tiny holes in their leaves. Once they have water and carbon dioxide, they can use energy from sunlight to make their food. The leftovers from making the plant food is another gas called oxygen. This oxygen is released from the leaves into the air. Take a look at the picture below to see this system in action.
