Question

Photosynthesis can take place in absence of

• A. Light
• B. ${CO}_2$
• C. Chlorophyll
• D. Oxygen

Answer 1

The correct option is D Oxygen

Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.

So based on the above oxygen is produced by the process of photosynthesis and it is not consumed during this process. Photosynthesis can take place in absence of oxygen.

So the answer is 'Oxygen'.
