a tree is a perennial plant with an elongated stem, or trunk, supporting branches and
leaves in most species. In some usages, the definition of a tree may be narrower,
including only woody plants with secondary growth, plants that are usable as lumber
or plants above a specified height. Trees are not a taxonomic group but include a variety
of plant species that have independently evolved a woody trunk and branches as a way to tower
above other plants to compete for sunlight.
A tree typically has many secondary branches supported clear of the ground by the trunk.
This trunk typically contains woody tissue for strength, and vascular tissue to carry materials
from one part of the tree to another. For most trees it is surrounded by a layer of bark which serves
as a protective barrier.
