Question

The absence of which of these will not affect photosynthesis–oxygen, carbon dioxide, water, chlorophyll, light? Give reasons.

Answer 1

The absence of oxygen will have no effect on the process of photosynthesis. This is because the photosynthetic process utilises water and carbon dioxide to produce oxygen and carbohydrate in the presence of chlorophyll and sunlight. Thus, oxygen is a product of photosynthesis and is not required for photosynthesis.
