Which gas is produced by plants during photosynthesis?

Explanation:
When plants carry out photosynthesis, light energy is used to convert carbon dioxide and water into glucose, and oxygen is released as a byproduct. In the light-dependent reactions, water is split to provide electrons, and the oxygen atoms combine to form O2 gas that exits the plant. The overall result is glucose plus oxygen. Carbon dioxide is consumed, not produced; nitrogen isn’t involved in this gas output, and hydrogen from water is used to build sugars rather than released as a free gas. So the gas released by plants during photosynthesis is oxygen.
