    A tree is a terrestrial lignified plant capable of developing by itself in height, generally beyond seven meters. Trees acquire by secondary growth a rigid structure composed of a trunk which generally branches into branches.
    The development in height and branching branches allow the trees to increase their capacity to exploit the airspace. The position of the leaves on several levels allows the tree to multiply the exchange surface for photosynthesis.
    Trees are perennial plants that can live for several years, from several decades to several centuries, and for some species several millennia.
