Tree is a consensual name to characterize a large botanical typology, usually comprising a borderline height equal to less than 4 meters and greater. reaching about 122 meters (current record of the largest tree observed in the world), represented by gigantic sequoias (genus Sequoiadrendro) existing in the north of the California.
Among other characteristics, a tree has a pivoting root, whose function is to provide resistance to the plant, in addition to having a woody main stem from which branches emitted from a certain height, having the ground level as a reference, extending to the apex of the crown, forming the arboreal extract containing sheets.
According to this description, only gymnosperms and dicotyledonous angiosperms have tree specimens. Since lower vegetables are essentially small, as well as monocotyledonous angiosperms are morphologically distinct, for example, palm trees: normally without secondary branches and a short crown in the stem region terminal.
Curiosity: It is estimated that some specimens of Sequoiadendron giganteum are more than 2000 years old, with 1,500 cubic meters in volume and trunk base with 11 meters in diameter.
