In herbaceous and the young stems of the woody plants, gas exchange is accomplished through stomata, or small pores in the surface of the epidermis. however, as woddy plants mature, lenticels develope underneath the stomata. These groups of spongy parenchyme cells allow for gas exchange after the epidermis has been sloughed off.

plants possess two types of lateral meristems both of whichadd to their girth. The first type, called the vascular cambium , produces components of the secondary xylem and secondary phloem. The other type, commonly called the cork cambium, produces the box-like, waxy cork cells that form the outer bark in woody plants.
