Tree Photo (樹相片集) A tree is a large, perennial, woody plant. 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.
