NEET BIOLOGY

Detailed explanation-1: -Once they have water and carbon dioxide, they can use energy from sunlight to make their food. The leftovers from making the plant food is another gas called oxygen. This oxygen is released from the leaves into the air.

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: -Six oxygen molecule is released as a waste product. This oxygen is produced due to splitting of water by the process of photolysis during light reaction.

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.
