Question

what do you mean by light reaction and dark reaction

Answer 1

Light reactions need light to produce organic energy molecules (ATP and NADPH). They are initiated by colored pigments, mainly green colored chlorophylls. ... This means Dark reactions will fail to continue if the plants are deprived of light for too long since they use the output of the initial light-dependentreactions.

Answer 2

Light Reaction- absorption of light energy by chlorophyll

Dark Reaction- reduction of carbon dioxide to glucose
