What is the outer covering of tree branches and stems called?

Explanation:
The main concept is recognizing the protective outer covering of a tree’s woody parts. The outer covering is bark. Bark protects the tree and is made up of the periderm, including cork that forms the outermost layer, plus inner bark that contains phloem. Xylem and phloem are internal vascular tissues involved in water and sugar transport, not the outer protective layer. Cortex is a tissue located inside the epidermis in some stems, not the outer covering of mature branches and stems.
