Explanation:
Detailed explanation-1: -Photosynthesis is the process of synthesis of food by plants using carbon dioxide and water in presence of sunlight and chlorophyll. Oxygen (O2) is released during the process as a waste product. Hence, oxygen is not essential for the process of photosynthesis.
Detailed explanation-2: -Photosynthesis: inputs – light energy, carbon dioxide, water. Outputs – glucose, oxygen.
