WebThe pericycle is the region consisting of one or more layers of cells which surround the vascular tissues. It is located between the endodermis and the vascular bundles. Pericycle is regarded as the limiting layer of stele; thus it forms the outermost part of intrastelar ground tissues, the other portions being the pith and medullary rays.
