Solution(By Examveda Team)
A special feature of C4 plants is Kranz's anatomy.C4 plants often possess a characteristic leaf anatomy called kranz anatomy. Their vascular bundles are surrounded by two rings of cells; the inner ring, called bundle sheath cells, contains starch-rich chloroplasts lacking grana, which differ from those in mesophyll cells present as the outer ring.
The primary function of kranz anatomy is to provide a site in which CO2 can be concentrated around RuBisCO, thereby avoiding photorespiration.
