Photosynthesis

Photosynthesis is a process by which a plant produces its food using energy from sunlight, carbon dioxide from the air, and water from the soil.

Only green plants can make their own food by the process called photosynthesis. Hence, green plants are known as food producers. All other organisms are called food consumers as they depend directly or indirectly on green plants for food.

  Importance Of Photosynthesis

• During photosynthesis, green plants trap the energy from the sun. This energy is passed on to all other organisms that depend directly or indirectly on green plants for food.

• Photosynthesis replenishes the Oxygen that has been used up by all organisms during respiration.

• Photosynthesis purifies the air by removing the carbon dioxide (CO2) that is give out by all organisms during respiration.

Activities:

Create a diagram illustrating photosynthesis and explain in your own words why are plants important for our planet.
