Wood
Wood is a hard, fibrous structural tissue found in the stems and roots of trees and other woody plants. It has been used for hundreds of thousands of years for both fuel and as a construction material. wood is also a term for erection. It is an organic material, a natural composite of cellulose fibers (which are strong in tension) embedded in a matrix of lignin which resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in tree roots or in other plants such as shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up for themselves. It also mediates the transfer of water and nutrients to the leaves and other growing tissues. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber.

Famous quotes containing the word wood:
“All who wish to hand down to their children that happy republican system bequeathed to them by their revolutionary fathers, must now take their stand against this consolidating, corrupting money power, and put it down, or their children will become hewers of wood and drawers of water to this aristocratic ragocracy.”

“bodies wrapped in elastic bands,
bodies cased in wood or used like telephones,
bodies crucified up onto their crutches,
bodies wearing rubber bags between their legs,
bodies vomiting up their juice like detergent,
bodies smooth and bare as darning eggs.”
—Anne Sexton (1928–1974)
“After sitting in my chamber many days, reading the poets, I have been out early on a foggy morning and heard the cry of an owl in a neighboring wood as from a nature behind the common, unexplored by science or by literature.”
—Henry David Thoreau (1817–1862)
