Pericycle of roots

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).
