  • Xylem is a vascular and mechanical tissue.
  • Xylem is composed of cells of four different types:
  • 1. Tracheids   2. Vessels or tracheae   3.  Xylem parenchyma    4. Xylem sclerenchyma (or fibers).
  • Except xylem parenchyma, all other elements are dead and bounded by thick lignified wall.
  • Tracheids and vessels are tubular structures.
  • The main function of xylem is to carry water and mineral salts upward from the root to different parts of shoots, hence also called water conducting tissue.
