This is not true. When driving at night, try not to look directly at high beams coming towards you and look to the lines in the road to stay on course. A light reaction strongly requires the presence of light source to produce cellular energy for the plant, whereas dark reaction occurs in the absence of light. Dark Reactions is the second phase in the process of photosynthesis following the light reaction. Dark reaction in photosynthesis is called so because (a) It can occur in dark also (b) It does not directly depend on light energy (c) It cannot occur during day light (d) It occurs more rapidly at night Dark reaction definition, the phase of photosynthesis, not requiring light, in which carbohydrates are synthesized from carbon dioxide. stroma.
