Botany: Stele types

admin Plant biology

In a vascular plant, the stele is the central part of the root or stem containing the tissues derived from the procambium. These include vascular tissue, in some cases ground tissue (pith) and a pericycle, which, if present, defines the outermost boundary of the stele. In other words, vascular bundle or the stele consists of three tissues: the pericycle, the …
