Pericycle in stem
Webpericycle: [noun] a thin layer of parenchymatous or sclerenchymatous cells that surrounds the stele in most vascular plants. The pericycle is a cylinder of parenchyma or sclerenchyma cells that lies just inside the endodermis and is the outer most part of the stele of plants. 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 … See more 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. See more In dicot roots, the pericycle strengthens the roots and provides protection for the vascular bundles.
