Give advantages of C4 cycle over C3 Cycle
(i) The C4 cycle is more efficient than the C3 cycle. (ii) C4 plants do not have photorespiration. (iii) In comparison to C3 plants, the C4 cycle may utilize C02 at relatively low quantities. (iv) The C4 cycle works in plants that are suited to high light intensity, high temperature, and low water availability; the C3 cycle cannot work under these conditions.
