Explanation:
Detailed explanation-1: -Oxygen is a by-product of photosynthesis and not a reactant, so photosynthesis can take place in the absence of oxygen.
Detailed explanation-2: -Oxygen is mainly released as a by-product by photolysis of water and released in the atmosphere. Thus, it is not required for photosynthesis.
Detailed explanation-3: -Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.
