The term tree bark refers to the tissues outside the vascular cambium. The inner bark is composed of secondary phloem, which in general remains functional in transport for only one year.
What is the bark of a tree made of?
It is composed mostly of dead cells and is produced by the formation of multiple layers of suberized periderm, cortical and phloem tissue. The rhytidome is especially well developed in older stems and roots of trees. In shrubs, older bark is quickly exfoliated and thick rhytidome accumulates.

Do all trees have bark?
The smooth, unbroken outer bark that all trees start out with is this cork layer of the periderm. As a tree grows, its wood thickens and pushes out against the bark that surrounds it. The different ways in which the outer bark adapts to this pressure is what gives each species its distinctive appearance.
