Kranz anatomy is present in the leaves of

  • A.C\(_{2}\) plants
  • B.C\(_{3}\) plants
  • C.C\(_{4}\) plants
  • D.CAM plants

Answer: C

Kranz anatomy is found in the leaves of C4 plants.

In C4 plants such as maize, sugarcane and sorghum, the vascular bundles are surrounded by a ring of large, chloroplast-rich bundle sheath cells, with mesophyll cells arranged around them, a wreath-like ('Kranz') arrangement. CO2 is first fixed in the mesophyll and then released in the bundle sheath, where the Calvin cycle runs.

C3 and CAM plants lack this specialised bundle sheath, and 'C2 plants' is not the standard category with Kranz anatomy.
