During photosynthesis, plants release which gas:

The correct answer is: Oxygen

• Photosynthesis is the process by which green plants make their own food in the form of glucose and other energy-rich compounds.
• It involves the conversion of carbon dioxide, water, and minerals into sugar and oxygen using sunlight. During this process, the light energy of the sun is transformed into chemical energy.
• The chemical energy is later on used as fuel to release energy that is needed to perform various life activities of living organisms.

> Carbon dioxide and water are used as raw materials during photosynthesis to manufacture complex carbohydrates such as sugars and in most of the cases, oxygen is released as a waste product. Hence, the process of photosynthesis involves the intake of carbon dioxide and the release of oxygen.
> The release of oxygen during the photosynthesis is due to photolysis of water in order to fill the gap in the photo system, which is caused by the excitement of the electron.
This reaction is often considered a reversible reaction and takes place in presence of sunlight.
> During the light reaction photosynthesis, oxygen is released. Water is split into oxygen and also as H+ protons and electrons. The electrons produced reduce the P680+ pigments in photosystem II after donating their excited electrons to primary electron acceptor. The H+ protons are then released into the stroma for later usage. The O2 molecules are released as waste from plants.
> Oxygen is released during the process of photosynthesis.
