A) few chloroplasts with thin walls so that gaseous exchange can take place
B) large number of chloroplasts with thick walls impervious to gaseous exchange
C) large number of chloroplasts and intercellular spaces
D) few chloroplasts with thick walls and no intercellular spaces
Correct Answer: A
Solution :
Leaves of\[{{C}_{4}}\]plants show specific type of anatomy, i.e., dimorphic chloroplast- Agranal, larger with intercellular spaces (bundle sheath cells) granal, small (mesophyll cell). This type of dimorphic anatomy of leaves is termed as Kranz anatomy. In\[{{C}_{4}}\]plant\[C{{O}_{2}}\]fixation occur twice firstly in mesophyll cells then in bundle sheath cells which posses larger number of agranal chloroplast and intercellular spaces. Hence, this type of\[C{{O}_{2}}\]fixation cycle is also known as dicarboxylic acid cycle.
