Question

Which of the following is absorbed by green plants during photosynthesis?

  1. Helium
  2. Nitrogen
  3. CO2 (Carbon Dioxide)
  4. O2

hintHint:

The gas that is expired during respiration.

The correct answer is: CO2 (Carbon Dioxide)


    • Carbon dioxide is the used during photosynthesis
    • Photosynthesis is the process by which plants take carbon dioxide and water and convert them into food and release oxygen in the presence of sunlight
    • During the process, water is oxidized and carbon dioxide gets reduced
    • As a result, water is converted to oxygen and carbon dioxide is converted into glucose or sugar
