Pericycle

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!

WebConiferous plant species that thrive in cold environments, like spruce, fir, and pine, have leaves that are reduced in size and needle-like in appearance. These needle-like leaves have sunken stomata (pits that allow gas exchange) and a smaller surface area: two attributes that aid in reducing water loss.

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.

WebPericycle – It is the outermost layer of the stele and is composed of a uniseriate layer of parenchymatous cells without intercellular spaces. Some dicots and hydrophytes do not bear pericycle. Several lateral roots and lateral meristem arise from the pericycle region (hence lateral roots are endogenous in origin).
