The Adaptive Advantage of the C4 Pathway of Photosynthesis Is

Question

The adaptive advantage of the C4 pathway of photosynthesis is it
A) avoids photorespiration.
B) decreases local osmotic pressure.
C) increases CO2uptake during the day.
D) does not require oxygen.
E) none of the above

Accepted Answer

The C4 pathway minimizes photorespiration by concentrating CO2 at the site of the Calvin cycle, which is an adaptive advantage in hot, dry environments where photorespiration would otherwise reduce photosynthetic efficiency.
