Photosynthesis is a two stage process. The first process is the Light Dependent Process (Light Reactions), requires the direct energy of light to make energy carrier molecules that are used in the second process.
The process of photosynthesis is broken up into two main groups of reactions: the light reactions which require light energy to operate, and the Calvin cycle which specifically takes carbon dioxide and turns it into organic molecules.
