Did you know?
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 vascular tissues it surrounds. In eudicots, it also has the capacity to produce lateral roots. Branch roots arise from this primary WebDicot Root: Part # 4. Pericycle: Endodermis is followed by one (e.g., Sunflower) or more (e.g., Mulberry) layers of pericycle. Pericycle is believed to represent the outer boundary of vascular strand. The cells of pericycle are thin-walled and parenchymatous in the young root. Pericycle is a very important layer. A part of the vascular cambium

It … WebPericycle cells may be used for storage, they contribute to the vascular cambium, and initiate the development of lateral roots. Consequently, lateral roots are developing endogenously and break tissues located outside, like aliens in the famous movie. Root phloem is arranged in

WebPericycle or outer boundary of vascular strand lies below the endodermis. Pericycle may be uniseriate (single layered, e.g., Maize) or multiseriate (multi-layered, e.g., Smilax). In monocots the pericycle does not form cambium. It only produces lateral roots. The pericycle is composed of thin-walled parenchymatous cells in the young root.
