Though there is no set definition regarding minimum size, the term generally applies to plants at least 6 m (20 ft) high at maturity and having secondary branches supported on a main stem or stems (see shrub for comparison). Most trees exhibit clear apical dominance, though this is not always the case (Mitchell, 1978).[1] Compared with most other plant forms, trees are long-lived. A few species of trees grow to 115 m (375 ft) tall and some can live for several thousand years. 樹是具有木質樹幹及樹枝的植物，可存活多年。一般將喬木稱為樹，有明顯直立的主幹，植株一般高大，分枝距離地面較高，可以形成樹冠。樹有很多種。樹的主要四部份是樹根、樹幹、樹枝、樹葉。樹根在地下。一棵樹有很多根。 Changed: Mar 08, 2007.
