Final answer:
Light is essential for photosynthesis by converting light energy into chemical energy, resulting in ATP and NADPH. Glucose is a product of the dark reaction in photosynthesis.
Explanation:
Role of Light in Photosynthesis:
Light is crucial in photosynthesis as it is absorbed by chlorophyll in the chloroplasts, initiating the light-dependent reactions. These reactions convert light energy into chemical energy in the form of ATP and NADPH.
Product of Dark Reaction:
One product of the dark reaction in photosynthesis is glucose, a carbohydrate formed through the fixation of carbon dioxide using the ATP and NADPH produced in the light reaction.
