Hi Garima
C4 plants differ from C3 plants wth respect to the substrate which accept the CO2 molecule.

The primary CO2 acceptor in C3 cycle is Ribulose bis phosphate (RUBP a 5 carbon compound) whereas in case of C4 cycle the primary acceptor of CO2 is Phosphoenol pyruvic acid (PEP a 3 carbon compound).
