WebThe pericycle is the outermost layer of the stele (or vascular cylinder). Although it is composed of nonvascular parenchyma or sclerenchyma cells, it is considered to be part of the vascular cylinder because it is produced by the procambium. See it in 3D! WebIn roots, the first cork cambium appears in the outermost layer of the vascular tissue system, called the pericycle ( see below Plant organs: Roots). The meristematic tissue of the cork cambium produces more and more derivatives of cork cells and parenchyma and displaces them into the outer margins of the plant body.
