The most distinctive cells found in xylem are the tracheary elements, that is tracheids and vessel elements. However, the xylem is a complex tissue of plants, which means that it includes more than one type of cell. This is why it is a tissue not a cell.
Xylem and phloem, the two conducting tissues of the plant vascular system, are of tremendous fundamental interest and economic importance. Xylem is the water-conducting tissue, and secondary xylem provides the raw material for the forest products industry.he growth of secondary xylem and phloem depends on the division of cells in the vascular cambium and results in an increase in the diameter of the root and stem.
