Xylem cells are elongated cells with lignified secondary thickening of the cell walls. Xylem cells are specialised for conduction of water, and first appeared in plants during their transition to land in the Silurian period more than 425 million years ago (see Cooksonia). The possession of xylem defines the vascular plants or Tracheophytes.
The nonliving portion of a plants vascular system that provides support and conveys xylem sap from the roots to the rest of the plant. Xylem is made up of vessel elements and/or tracheids, water-conducting cells.Primary xylem is derived from the procambium.Secondary xylem is derived from the vascular cambium in plants exhibiting secondary growth.DEAD CELLS MOVES WATER AND MINERALS UP FROM THE ROOTS. osmotic pressure caused by the buildup of solutes in the xylem of roots; root xylem up solutes, down water, therefore water in soil diffuses into root; pressure in root xylem forces water up through stem xylem.
