Which gas do plants release during photosynthesis?
Answer and explanation
Correct answer: Oxygen
The governing concept is the overall reaction of photosynthesis. Green plants use light energy to convert carbon dioxide and water into carbohydrate, and oxygen is formed as a by-product, mainly from the splitting of water. It diffuses out through stomata, so option A is correct. Carbon dioxide is a reactant, while nitrogen and ammonia are not the normal gaseous product of photosynthesis.
