Which gas is used as a reactant during photosynthesis in plants?
Answer and explanation
Correct answer: Carbon dioxide
In photosynthesis, carbon dioxide reacts with water in the presence of sunlight and chlorophyll to form glucose and oxygen: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂. Thus, carbon dioxide is a gaseous reactant. Oxygen is mainly released as a product, while nitrogen and hydrogen are not the gaseous reactants in this standard equation.
