Concept:Photosynthesis is the process by which green plants use light energy to convert carbon dioxide and water into glucose.
Explanation:Light energy is essential because it drives the entire reaction.
Without light, the plant cannot split water molecules or make glucose.
The main food product made by photosynthesis is glucose (
C6H12O6).
Oxygen is not the main product; it is only released as a by-product.
Plants absorb water from the soil through their roots, not from the atmosphere.
Carbon dioxide is the gas that plants take in from the atmosphere.
Chlorophyll is the green pigment needed to trap light energy.
A leaf without chlorophyll cannot absorb sunlight, so it cannot photosynthesize.
Thus, the correct statement is that photosynthesis occurs in the presence of light energy.
Answer:Option A.
