Vedclass · Answer

(D) : $C_4$ plants exhibit $Kranz$ anatomy,where the mesophyll is undifferentiated and arranged in concentric layers around the vascular bundles. These bundles are surrounded by large bundle sheath cells in a wreath-like manner.In these plants,the initial fixation of $CO_2$ occurs in the mesophyll cells.The primary acceptor,phosphoenolpyruvate $(PEP)$,combines with $CO_2$ to form oxaloacetic acid $(OAA)$,which is subsequently reduced to malic acid.Malic acid is then translocated to the bundle sheath cells for further decarboxylation.

In leaves of $C_4$ plants,malic acid synthesis during $CO_2$ fixation occurs in:
