Describe the structure of stele in maize root


The stele is bounded by an endodermis and pericycle. Endodermal cells are barrel shaped and have casparian thickenings on their radical and tangential walls. Pericycle is represented by a single layer of thin walled parenchyma cells.

The vascular bundles are many in number (polyarch) and radial with exarch xylem. In the centre of the stele is a parenchymatous pith.
