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 role of bark?
Bark is analogous to an animal’s skin. Its purposes are conserving water and protecting the tree’s essential living systems from temperature extremes and storms as well as from attacks by diseases, animals and insects. Some tree species have extra-thick bark that protects the tree from brush fires.

Bark is the outer layer of the trunk of a tree. Trees have an inner and an outer layer of bark. The inner layer of bark is alive and continues to grow as the tree grows. It contains a tissue called phloem.
Why is it called tree bark?
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.
Can a tree survive without bark?
Without the protection of the bark, the phloem can no longer send that energy to the roots. If the roots don’t receive this energy, it can no longer transmit water and minerals up the tree to the leaves. The upper part of the tree will begin to die while the roots feed off the nutrients it has stored.
Where is bark of a tree?
Bark is the outermost layers of stems and roots of woody plants. Plants with bark include trees, woody vines, and shrubs. Bark refers to all the tissues outside the vascular cambium and is a nontechnical term. It overlays the wood and consists of the inner bark and the outer bark.

Heartwood gives the tree ‘backbone’ and is good at resisting rot and insect attack. As phloem dies it is pressed outwards and becomes part of the bark. Many trees also have a cork cambium layer, outside the first one. Its job is to produce cork, which also forms a major part of bark.

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.
Do trees grow new bark?
The cambium cell layer is the growing part of the trunk. It annually produces new bark and new wood in response to hormones that pass down through the phloem with food from the leaves. These hormones, called “auxins”, stimulate growth in cells.
