A layer of cells just inside the endodermis of a root that may become meristematic and begin dividing again.
Gr. peri: around + kyklos: ring or circle] • In plant roots, tissue just within the endodermis, but outside of the root vascular tissue. Meristematic activity of pericycle cells produces lateral root primordia.
Root tissue immediately inside the endodermis and outside the vascular tissue that consists of parenchyma cells and is the site of lateral root formation.
PEAR-ee-si-kel A ring of parenchyma cells in a root's cortex that produces branch roots that burst through the cortex and epidermis into the soil. 548
the outer boundary of the stele found just inside the endodermis
Found in the stele of plants, the pericycle is a cylinder of cells that lies just inside the endodermis. It conducts water and nutrients inward to the vascular tissue. In dicots, it is also has the capacity to produce lateral roots.
