Xylem vessels are made up of cells known either as tracheids or vessel members. Preview this quiz on Quizizz. Connections between xylem vessels represent important links in the vascular network, but the complexity of three-dimensional (3D) organization has been difficult to access. Furthermore, the water flow rate in xylem vessels of plants with and without Si was compared. The living cells around the xylem vessels in the root use active transport to pump the mineral salts or ions into the vessels. Xylem vessels are made up of cells known either as tracheids or vessel members. Anatomical Drawings Of A Fetal Pig.
