उत्तर
Tracheary elements are the elongated cells of xylem tissue. They are of two types:
(i) Vessels: These are long tube-like structures that are formed by a row of cells placed end to end. The transverse walls between the vessel elements are completely dissolved forming water pipes.
(ii) Tracheids: These are elongated cells with tapering ends. Since their end walls have closed ends, water has to pass from cell to cell via pits.
Both these elements are involved in the conduction of water.
