Xylem is composed of four main types of elements: tracheids, vessels, xylem parenchyma, and xylem fibres. Among these, only xylem parenchyma cells are living cells.
Tracheids and vessels are the main water-conducting elements and are dead, hollow tubes at maturity. Xylem fibres are typically dead and provide mechanical support. Xylem parenchyma cells are involved in storage of food materials (starch, fats) and lateral conduction of water and minerals.
