Plants prepare their food through the process of photosynthesis. Photosynthesis requires sunlight, water, carbon dioxide, and chlorophyll. The chapter discusses how plants use these factors - absorbing water through their roots and carbon dioxide from the air, while using chlorophyll and sunlight to produce food and release oxygen. A mind map and video are also used to illustrate the process of photosynthesis for the students.

3. PHOTOSYNTHESIS
The process by which plants prepare
their food with the help of sunlight,
chlorophyll (green coloured pigment
present in the leaves), water and
carbon dioxide is called
photosynthesis.

7. PHOTOSYNTHESIS
• Photosynthesis is the process by which plants make their
food.
• Plants use water that is absorbed from soil with the help of
roots.
• Plants take in carbon dioxide from the air.
• Plants get sunlight from the sun.
• Chlorophyll is the green coloured pigment present in the
leaves.
• By using water, sunlight, carbon dioxide and chlorophyll
plants make their food and give out oxygen.
