Detailed explanation-1: -Oxygen is a waste product of photosynthesis.

Detailed explanation-2: -Some of the oxygen produced in the process of photosynthesis is used in respiration by the leaf cells but the major portion of it is not required and it diffuses out into the atmosphere through the stomata. Therefore, it may be called a waste product of photosynthesis.

Detailed explanation-3: -Raw materials required for photosynthesis are carbon dioxide and water. Oxygen is produced as a waste product.

Detailed explanation-4: -Carbon dioxide is a waste product of aerobic respiration in plant cells.

Detailed explanation-5: -Carbon dioxide is the waste product involved in the aerobic respiration of the plants whereas oxygen is the waste product during the process called photosynthesis. Photosynthesis is the process by which the plants take up the light and that light is converted into the chemical energy to meet the requirements of food.
