Answer
This statement is false. The light-independent reactions, also known as the Calvin cycle, do not require water as the initial reactant. Instead, they primarily use carbon dioxide, and while water is involved indirectly, it is not a direct reactant in these reactions.
Step 2
B. the light independent reactions occur in the inner membrane area.

Answer
This statement is also false. The light-independent reactions occur in the stroma of the chloroplast, not in the inner membrane area.
Step 3
C. the final product of the light reaction is glucose.

Answer
This statement is incorrect. The light reactions of photosynthesis produce ATP and NADPH, not glucose. Glucose is synthesized later during the light-independent reactions.
Step 4
D. the light reactions occur in the grana.

Answer
This statement is true. The light reactions of photosynthesis take place in the thylakoid membranes located within the grana of the chloroplasts. Therefore, this statement is correct.
