Kranz anatomy is typical of

A.
C4 plants
Answer
B.
C3 plants
C.
C2 plants
D.
CAM plants

Answer: Option A

Solution

Answer: Option A
Solution:
Kranz's anatomy is typical of C4 plants.
C4 plants often possess a characteristic leaf anatomy called kranz anatomy, from the German word for the wreath. 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.
