Rice- C 3 -Mesophyll-Day, Pineapple-CAM-Mesophyll-Night, Sugarcane- C 4 -Bundle sheath-day

Rice- C 3 -Mesophyll-Day, Pineapple-CAM- Mesophyll-Night, Sugarcane- C 4 - Mesophyll-Day

Rice- C 4 -Mesophyll-Day, Pineapple- C 3 -Bundle sheath-Night, Sugarcane-CAM-Bundle sheath-Day

Rice-CAM-Mesophyll-Day, Pineapple-CAM-Mesophyll-Day, Sugarcane- C 4 -Bundle sheath-Day

Assertion (A): In C 3 plants photosynthesis is more than C 4 plants. Reason (R): C 4 plants have a shorter CO 2 fixation cycle.

Both (A) and (R) are true (R) is correct explanation of (A).
