What special anatomical features are displayed by leaves of $C_4$ plants? How do they provide an advantage over the structure of $C_3$ plants?

(N/A) $C_4$ plants exhibit a unique leaf anatomy known as $Kranz$ anatomy.
In $Kranz$ anatomy,the bundle sheath cells form several layers around the vascular bundles,characterized by a large number of chloroplasts,thick walls impervious to gaseous exchange,and no intercellular spaces.
$C_4$ plants possess two types of chloroplasts: agranal chloroplasts in bundle sheath cells and granal chloroplasts in mesophyll cells.
This structure provides an advantage by minimizing photorespiration,which is a wasteful process common in $C_3$ plants.
The bundle sheath cells maintain a high concentration of $CO_2$ around the enzyme $RuBisCO$,ensuring it functions as a carboxylase rather than an oxygenase.
Consequently,$C_4$ plants are more efficient in photosynthesis under high temperatures and high light intensities compared to $C_3$ plants.
