Several biotopes (an area of uniform environmental, physical conditions providing habitat for a specific assemblage of plants and animals) are defined largely by the trees that inhabit them; examples are rainforest and taiga.
The oldest trees are determined by growth rings, which can be seen if the tree is cut down or in cores taken from the edge to the center of the tree.
Trees also play an important role in many of the world's religions and mythologies.
Exogenous trees, which comprise the great majority of modern trees (all conifers and broadleaf trees), grow by the addition of new wood outwards, immediately under the bark.
