Origin of xylem:
1870–75; < G < Gk xýl(on) wood (see phloem )
the woody part of plants: the supporting and water-conducting tissue, consisting primarily of tracheids and vessels
A vascular tissue in land plants primarily responsible for the distribution of water and minerals taken up by the roots; also the primary component of wood.

Xylem is one of the two types of transport tissue in vascular plants. The word xylem is derived from the Greek word ξύλον, 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.
U.S. National Library of Medicine
Plant tissue that carries water up the root and stem. Xylem cell walls derive most of their strength from LIGNIN. The vessels are similar to PHLOEM sieve tubes but lack companion cells and do not have perforated sides and pores.
