Tree bark has the function to protect the living parts of the tree, located just below the bark. In the outermost area or cambrium, new wood is generated. Below this is the sapwood, which contains the vascular tissue which has the function of conducting water upwards from the root system and food downwards from the leaves. When tree bark is cut deeply, the xylem, which conducts water upwards from the root system will be unable to transport water up to the leaves in the aerial part of the tree. Therefore, the leaves will dry up and the tree will die.
