Photosynthesis - An Overview
There are 3 basic types of photosynthesis:  C3, C4, and CAM.  Each has advantages and disadvantages for plants living in different habitats.
All 3 forms of photosynthesis are based on two pathways.  The first are the light reactions, where energy from the sun is absorbed by the chlorophyll of the plant, and the energy is transferred to hydrogen ions which are split off from water (Oxygen is produced at this point).  The second pathway is the so-called "dark reactions" - better known as carbon fixation or the Calvin Cycle.  Here, carbon dioxide is taken from the air and combined to make sugars.  The energy absorbed in the light reactions is used to drive this process, with the end result being sugar molecules with energy stored in the carbon-carbon bonds of the sugar.  The 3 types of photosynthesis differ in details of how these processes are carried out.
"Normal: photosynthesis is carried out by most plants growing in areas with sufficient......
