Although it is composed of non-vascular parenchyma cells, it's still considered part of the vascular cylinder because it arises from the procambium as do the vascular tissues it surrounds.[citation needed]

Location
The pericycle is located between the endodermis and phloem in plant roots. In dicot stems, it is situated around the ring of vascular bundles in the stele.[1]
Function
In dicot roots, the pericycle strengthens the roots and provides protection for the vascular bundles.[citation needed]
In dicot root, the vascular cambium is completely secondary in origin, and it originates from a portion of pericycle tissue.[citation needed]
The pericycle regulates the formation of lateral roots by rapidly dividing near the xylem elements of the root.[2]
It has been known to often be confused with other parts of the plant. However, its unique ring structure allows it to be more easily identified.[citation needed]
Past efforts to isolate such tissue have been successful. Monocot roots rarely branch, but can, and this branch will originate from the pericycle.[citation needed]
