(Botany) botany the stage of photosynthesis involving the reduction of carbon dioxide and the dissociation of water, using chemical energy stored in ATP: does not require the presence of light. Compare light reaction

The light-independent reaction takes considerably longer to occur because it involves migration of the components from the site of production to the site of use.
The next element in the process is to examine the light-independent reactions.
Once produced, these energy-rich compounds must then migrate to the energy transfer point in the leaf and release their energy to drive the light-independent reactions or dark reaction in the chloroplast stoma to convert carbon dioxide into glucose through a complex series of reactions that all first-year biology students learn as the Calvin Benson cycle.
