WebFunction: The pericycle supports the root, protects its vascular structures, stores nutrients, and facilitates root growth. Pericycle cells can divide and give rise to lateral roots in both monocots and dicots. In dicots, the pericycle also generates meristem cells that support secondary root growth and the cambium that produces xylem and phloem.
