Xylem is one of the two types of transport tissue in vascular plants. Xylem is derived from Greek word "xylon" meaning wood. Xylem is used for the transport of water and dissolved minerals from the roots to the rest of the plant.It consists of a variety of specialized, water-conducting cells known as tracheary elements.
