प्रश्न
Answer the following question.
A gas is released during photosynthesis. Name the gas and also state the way by which the gas is evolved.
उत्तर
Oxygen(O2) is released during photosynthesis.
During photosynthesis, plants absorb carbon dioxide and sunlight to produce carbohydrates. The solar energy trapped by chlorophyll breaks down water molecules by the process of photolysis. It is a type of photo-oxidation reaction that releases oxygen. This released oxygen gets emitted in the atmosphere.
