A process that makes important difference between C3 and C4 plants is
A
Photorespiration
B
Transpiration
C
Glycolysis
D
Photosynthesis
Detailed Solution
In $C_3$ plants RuBisCO also binds $O_2$, so photorespiration occurs and some fixed carbon is lost.
$C_4$ plants concentrate $CO_2$ at the site of RuBisCO in the bundle sheath cells, so photorespiration does not occur.
This lack of photorespiration is the important difference; it gives $C_4$ plants higher productivity.
