Cross-section through a woody stem with secondary growth. A vascular cambium has been formed which deposits xylem (to the internal side) and phloem (to the external side). The cork cambium under the epidermis forms cork to the outside. The bark contains all tissues outside the vascular cambium: phloem and cork layer.
