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   is the vascular tissue responsible for the transport of water and  nutrients from the roots in the soil to the above-ground parts of  the plant. Hormones and othe â¦ r small molecules also travel through  the xylem as they are moved throughout the plant.   he main purpose of the xylem is to transport water and minerals up the stem, from theroots to the leaves.
