A tree trunk has three main zones; the bark, the sapwood and the heartwood. Trees are basically triangular in shape and they gain height by growing outwards and upwards. At the start of each growing season, a new layer is added to the outside of the wood so that every part of the tree gets bigger – roots, trunk, branches and twigs.
