Question
In leaves of C4 -plants malic acid synthesis during CO2 -fixation occurs in
-
epidermal cells
-
mesophyll cells
-
bundle sheath
-
guard cells
Solution
B.
mesophyll cells
C4- plants show Kranz anatomy. In the leaves of C4- Plants the vascular bundles are surrounded by bundle sheath of parenchymatous cells, which in turn are surrounded by mesophyll cells. In C4 -plants and Hatch and Stack pathway involve two carboxylation reaction one taking place in the chloroplast of mesophyll cells and other in the chloroplast of bundle sheath cells.
