Question : The productivity of C_(4) is more than C_(3).

1.	Question : The productivity of C_(4) is more than C_(3).
Answer» Solution :In `C_(4)` pathway PROCESS the concentration of `CO_(2)` of chloroplast of bundle sheath cells keep on increasing. In these cells biosynthetic process of carbon fixation occurs, so more `CO_(2)` is obtained, more carbohydrate is produced. Moreover, STRUCTURE of Kranz tissue prevents `O_(2)` produced in lightreaction of mesophyll cells to bundle sheath cells. So there is no POSSIBILITY of photorespiration, Thus the productivity of `C_(4)` pathway is more than `C_(3)`.
