Detailed explanation-1: -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-2: -Raw materials required for photosynthesis are carbon dioxide and water. Oxygen is produced as a waste product.

Detailed explanation-3: -Carbon dioxide is a waste product of aerobic respiration in plant cells.

Detailed explanation-4: -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.

Detailed explanation-5: -Because plants don’t use oxygen, they release it as a waste product through the same pores they used to take in carbon dioxide. This is very helpful for humans and other animals who breathe the oxygen that plants release into the atmosphere.
