Xylem
Xylem is one of the two types of transport tissue in vascular plants, phloem being 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.The basic function of xylem is to transport water, but it also transports some nutrients.
