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:
“This is the poem of the air,
Slowly in silent syllables recorded;
This is the secret of despair,
Long in its cloudy bosom hoarded,
Now whispered and revealed
To wood and field.”
—Henry Wadsworth Longfellow (1809–1882)
“It would be as wise to set up an accomplished lawyer to saw wood as a business as to condemn an educated and sensible woman to spend all her time boiling potatoes and patching old garments. Yet this is the lot of many a one who incessantly stitches and boils and bakes, compelled to thrust back out of sight the aspirations which fill her soul.”
—Sarah M. Grimke (1792–1873)
“The most serious charge which can be brought against New England is not Puritanism but February.”
—Joseph Wood Krutch (1893–1970)
