How do c3 and c4 plants differ in their capacity for photosynthesis?
Similarly, it is asked, how does a c4 plant differ from a c3 plant?
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).
Likewise, why are c4 plants more efficient in photosynthesis? The C4 pathway is certainly more efficient than the C3 pathway in the sense of carbon fixation. The enzyme responsible for this step is RuBisCO. In C4 plants, the inner cells get only carbon dioxide in the form of malate. This avoids the oxygenation process and, hence, makes this pathway more efficient.
Likewise, people ask, why do c4 plants show more efficient photosynthesis as compared to c3 plants?
In C3 plants, chloroplasts are not present in the bundle sheath cells. Also, In C4 plants, photosynthesis occurs even when pores called stomata are closed. C4 plants show high efficiency in photosynthesis than the C3 plants because they contain more chloroplasts.
How are c3 c4 and CAM plants similar?
Cells involved in a C3 pathway are mesophyll cells and to that of the C4 pathway are mesophyll cell, bundle sheath cells, but CAM follows both C3 and C4 in same mesophyll cells. C3 can be seen in all photosynthetic plants, while C4 is followed by tropical plants and CAM by Semi-arid condition plants.
