Which gas is released during the process of photosynthesis?
Which gas is released during the process of photosynthesis?
(a) Carbon dioxide
(b) Oxygen
(c) Nitrogen
(d) Ammonia
Oxygen is the gas released during photosynthesis. Plants, algae, and certain bacteria produce it when they turn sunlight, water, and carbon dioxide into chemical energy (glucose). This process splits water molecules during light-dependent reactions, which releases oxygen into the atmosphere.
