C3 vs C4 Plants. Photosynthesis is the light driven reaction that converts carbon dioxide and water in to energy rich sugars. The process is coupled to the oxidation of water yielding oxygen as a biproduct.4 plants are much more efficient at capturing carbon dioxide. C4 photosynthesis is found in both monocot and dicot species. In contrast to C3 plants, the first stable product formed during photosynthesis is oxaloacetic, which is a C4 compound.
