Which gas do plants release during photosynthesis?

Explanation:
Photosynthesis releases oxygen as a byproduct. In the light-dependent reactions, water is split, producing oxygen gas that exits the plant, while the energy from light drives the production of sugars from carbon dioxide. The overall equation shows this gift of oxygen: water plus carbon dioxide, with light, yields glucose and oxygen. So the gas given off by plants during photosynthesis is oxygen. Carbon dioxide is actually used up to make sugars, nitrogen isn’t released as a gas in this process, and hydrogen gas isn’t the product of photosynthesis.
