2. There are two main phases of photosynthesis: the light-dependent phase or light reaction, and the light-independent phase or dark reaction.
3. Dark reaction occurs in the stroma of the chloroplast.
4. In light-independent phase reduction of carbon dioxide to carbohydrates takes place.
5. The dark reaction is not dependent on light and may occur in the absence or presence of light.
