Xylem

Xylem is one of the two types of transport tissue in vascular plants (phloem is the other). The word xylem is derived from the Greek word ξύλον (xylon), meaning "wood"; the best-known xylem tissue is wood, though it is found throughout the plant. Its basic function is to transport water, but it also transports some nutrients through the plant.
