<P> Between the xylem and phloem is a meristem called the vascular cambium . This tissue divides off cells that will become additional xylem and phloem . This growth increases the girth of the plant , rather than its length . As long as the vascular cambium continues to produce new cells , the plant will continue to grow more stout . In trees and other plants that develop wood , the vascular cambium allows the expansion of vascular tissue that produces woody growth . Because this growth ruptures the epidermis of the stem , woody plants also have a cork cambium that develops among the phloem . The cork cambium gives rise to thickened cork cells to protect the surface of the plant and reduce water loss . Both the production of wood and the production of cork are forms of secondary growth . </P>
