उत्तर
Dark reaction in photosynthesis is called so because it does not depend on light energy.
Explanation:
Splitting of the water molecule and formation of ATP is directly driven by light and hence are called light reactions. The rest of the steps are not directly light-driven and hence are called dark reactions (as per convention). This does not mean that they happen in the dark and not during the day.
