The Inner Bark
sapwood
In general, it does not. As the trunk of the tree goes bigger, the bark splits and that is why it is so rough. However, some trees do shed its bark. Sycamore and Crepe Myrtles(which may be a bush instead of a real tree).
bark
Periderm is another term for tree bark. It comprises tissue surrounding cork cambium.
The bark of the tree is the outer protective coating,beneath the the bark is the living fluid nutrient transport system from roots to leaves. Cork comes from the bark of the Mediterranean cork oak ,Quercus suba
* The bark is a tree's "skin". Removal of the bark (in most cases) increases the evaporation of necessary fluids, and allows for easier attack by predators / parasites. * also its removal will damage the phloem tissue starving the roots.
Bark is the outer layer of the living tissue of the tree. As the living layer grows it pushes the bark layer to the outside, which stretches and cracks the bark. Bark protects the tree from things that would harm the living tissue of the tree. Dangers include pests such as beetles and termites, and the heat from fires. Bark also slows the evaporation from the living tissues that would make the sap too thick to travel down to the roots. Without bark, many trees could not survive in the hot, cold, pest infested areas that they live in.
The layer under the bark carries the nutrients to the tree so if this is stopped the tree will die. The layer under the bark carries the sap to the rest of the tree if this is disturbed the tree will die.
