NEET BIOLOGY

Detailed explanation-1: -Carbon dioxide is a gas found in the air; plants can take in this gas through tiny holes in their leaves. 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.

Detailed explanation-2: -The oxygen that is produced is released from the same tiny holes through which the carbon dioxide entered. Even the oxygen that is released serves another purpose. Other organisms, such as animals, use oxygen to aid in their survival. The whole process of photosynthesis is a transfer of energy from the Sun to a plant.

Detailed explanation-3: -Photosynthesis is the process by which green plants synthesise their own food from carbon dioxide and water in the presence of sunlight and chlorophyll. During this process, oxygen is released as a by-product.

Detailed explanation-4: -Plants, during the process of photosynthesis, take up carbon dioxide from the atmosphere and use sunlight along with it to make their food. The gas produced as a result of photosynthesis is oxygen.

Detailed explanation-5: -The products of photosynthesis are glucose and oxygen. (This is good news for organisms like humans and plants that use oxygen to carry out cellular respiration!)
