* It is a vascular and mechanical tissue.
* The main function of xylem is to carry water and mineral salts upwards from the root to different parts of shoot.
* It is composed of cells of four different types- 1. Vessels
                                                                    2. Tracheids
                                                                    3. Xylem parenchyma
                                                                    4. Fibre
* Since walls of the Tracheids, vessels and fibres of Xylem are lignified, they give mechanical strength.
