Cortex: It is made up of several layers of parenchymatous cells that contain starch grains.

Endodermis: It is made up of single layer of cells provided with Casparian strips.

Pericycle: It is a single layer of closely fitted parenchyma cells located just beneath the endodermis.

Vascular bundles: These are radial bundles arranged in a ring. The number of xylem and phloem bundles are generally more than six. The arrangement of xylem is exarch.
