A) epidermal cells
B) mesophyll cells
C) bundle sheath
D) guard cells
Correct Answer: B
Solution :
\[{{\text{C}}_{\text{4}}}\text{-}\]plants show Kranz anatomy. In the leaves of \[{{\text{C}}_{\text{4}}}\text{-}\]plants, the vascular bundles are surrounded by bundle sheath of parenchymarous cells, which in turn are surrounded by mesophyll cells. In \[{{\text{C}}_{\text{4}}}\text{-}\]plants, the Hatch and Slack pathway involves two carboxylarion reaction one taking place in chloroplast of mesophyll cells and other in chloroplast of bundle sheath celts. The initial \[C{{O}_{2}}\]fixation occurs in mesophyll cells where primary \[C{{O}_{2}}\]acceptor is phosphoenol pyruvate and formed oxalacetate. The oxaloacetate is reduced to malic acid. From chloroplasts of mesophyll cells, the malic acid is transferred to chloroplast of bundle sheath cells and decarboxylated to form \[C{{O}_{3}}\]and pyruvic add. The \[C{{O}_{2}}\] is again fixed by \[{{\text{C}}_{\text{3}}}\text{-}\]cycle.
