      Thefirst hypothesis abouttherole of light in photosynthesis came very appropriately from Jan Ingenhousz, who some years earlier had madethe epochal discovery that it is "the influence of the light of the sun upon the plant" (1) that is responsible for the "restorative" effect of vegetation on "bad" air-an observation first made in 1771 by Joseph

      Light Reactions Dark Reactions The light-dependent reaction is the rst stage of photosynthesis. It uses light energy and takes place in the thylakoid membranes of the organelles called chloroplasts. Light-independent reaction is the second stage of photosynthesis. It converts carbon dioxide and other compounds into glucose. It occurs in stroma.
