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.
All the reactions of photosynthesis that are not directly dependent upon light are known as the dark reactions. The dark reactions occur whether there is light present or not. The dark reactions occur in the part of the chloroplast known as the stroma.
