Question

Dark reaction of photosynthesis does not need light explain

Answer 1

Answer:

In photosynthesis only the light reactions need light to produce necessary food and energy. The dark reactions however do not need light as they instead use up the energy created in the light reactions to make glucose(or sugar molecules).

Answer 2

Dark reaction does not mean that it occurs in the absence of light i.e., at night. Infact, it is the reaction occurring simultaneously with light reaction. It a chemical process occurring independent of light. This reaction is completely based on enzymes.
