Question

Sources of oxygen given out in photosynthesis

Answer 1

• In this process, carbon dioxide and water react, in presence of sunlight, to generate glucose molecules and oxygen.
• Thus, the source of oxygen from plants is the chemical reaction of photosynthesis, which has CO2 and water as the reactants.

Answer 2

In this process, carbon dioxide and water react, in presence of sunlight, to generate glucose molecules and oxygen. Thus, the source of oxygen from plants is the chemical reaction of photosynthesis, which has CO2 and water as the reactants.
