Select the incorrect statement as far as kranz anatomy is concerned.

Options

A. Undifferentiated mesophyll occurs in concentric layers around vascular bundles.
B. Centrifugal chloroplasta are present in bundle sheath cells.
C. Large sized bundle sheath cells are arranged in a wreath-like manner in one to several layers.
D. Chloroplasts of bundle sheath cells possess welldeveloped grana lamellae.

Answer

D

Explanation

Kranz anatomy is a characteristic of `C_(4)` plants, In kranz anatomy, the mesophyll is undifferentiated and its cells occur in concentric layers around vascular bundles. Vascular bundles are surrounded by large sized bundle sheath cells which are arranged in a wreath-like manner in one to several layers. The chloroplasts of mesophyll cells are smaller, they have well developed grana and a peripheral reticulum but no strach.
