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:

“I was with Hercules and Cadmus once,
When in a wood of Crete they bayed the bear
With hounds of Sparta: never did I hear
Such gallant chiding; for besides the groves,
The skies, the fountains, every region near
Seemed all one mutual cry. I never heard
So musical a discord, such sweet thunder.”
—William Shakespeare (1564–1616)

“It is not night when I do see your face,
Therefore I think I am not in the night;
Nor doth this wood lack worlds of company,
For you, in my respect, are all the world.”
—William Shakespeare (1564–1616)

“Ashtrays to cry into,
the suffering brother of the wood walls,
the forty-eight keys of the typewriter
each an eyeball that is never shut,
the books, each a contestant in a beauty contest,
the black chair, a dog coffin made of Naugahyde....”
—Anne Sexton (1928–1974)
