The chemical equation shown represents photosynthesis. A+ Water + Light X BaOH green What is the role of substance A in photosynthesis? (3 points) It traps light energy from the atmosphere. It combines with water to form glucose. It cools the atmosphere by changing into vapor. It changes into hydrogen in the presence of light

The correct answer is: It traps light energy from the atmosphere.<br /><br />In the given chemical equation, substance A is not specified, but based on the options provided, we can infer that substance A is likely chlorophyll or a similar pigment involved in photosynthesis.<br /><br />Chlorophyll is a pigment found in the chloroplasts of plant cells. Its primary role in photosynthesis is to absorb light energy from the atmosphere and convert it into chemical energy. This energy is then used to drive the chemical reactions that produce glucose and oxygen.<br /><br />Therefore, the role of substance A in photosynthesis is to trap light energy from the atmosphere and convert it into chemical energy.
