Question

which part of the photosynthetic cycle does not require sunlight?
a. chemosynthesis
b. photon collisions
c. calvin cycle
d. light reaction

Explanation:

The Calvin cycle, also known as the dark - reaction, can occur without sunlight. It uses ATP and NADPH from the light - reaction to fix carbon dioxide into glucose. Chemosynthesis is not part of the photosynthetic cycle. Photon collisions are related to light - reactions which need sunlight. Light reactions require sunlight to generate energy - carrying molecules.

Answer:

C. Calvin cycle
