WebbThe stele (or vascular cylinder) is in the central region of the root, where the xylem and phloem develop. In dicot roots, the stele contains clusters of phloem arranged around the central xylem. Dicot steles contain an additional component, not present in monocot roots, called cambium. Dicot root steles do not contain pith. See it in 3D! Pericycle
