Why same amount of co2 fixed c4 plant used half amount of water in comparison to c3 plant
Answers
In C4 plants photorespiration does not occur. This is because they have a mechanism that increases the concentration of CO2 at the enzyme site. ... The C4 pathway is certainly more efficient than the C3 pathway in the sense of carbon fixation.
they can photosynthesize over a wider range of wavelength in sunlight and hence produce more products. C4 plants are more productive than C3 because, Presence of ' kranz anatomy' - both mesophyll cells and bundle sheath cells are present. They lack photorespiration
The perennial grasses can be classified as either C3 or C4 plants. These terms refer to the different pathways that plants use to capture carbon dioxide during photosynthesis. All species have the more primitive C3 pathway, but the additional C4 pathway evolved in species in the wet and dry tropics.
C3 plants are those plants where the first product of photosynthesis is a 3 carbon compound i.e. phosphoglyceric acid (PGA) while C4 plants are those plants where the first product of photosynthesis is a 4 carbon compound i.e oxaloacetic acid (OAA).
