Detailed explanation-1: -Summary. The light reactions capture energy from sunlight, which they change to chemical energy that is stored in molecules of NADPH and ATP. The light reactions also release oxygen gas as a waste product.
Detailed explanation-2: -Glucose is a simple sugar molecule which can be combined with other glucose molecules to form large carbohydrates, such as starch. Oxygen is a waste product of photosynthesis. It is released into the atmosphere through the stomata.
Detailed explanation-3: -Through photosynthesis, they use sunlight and carbon dioxide to make food, belching out the oxygen that we breathe as a byproduct. This evolutionary innovation is so central to plant identity that nearly all land plants use the same pores-called stomata-to take in carbon dioxide and release oxygen.
Detailed explanation-4: -Stomata’s main function is the exchange of gases. They are formed as a gap between two cells known as guard cells – the guard cells adapt their shape to open and close the stomata. They not only allow carbon dioxide to diffuse into the leaf but also allow water and oxygen to diffuse out of the leaf.
