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 are the two types of vascular tissues that are present in plants. They are responsible for transporting water, minerals, food and other organic materials between the roots, stems and leaves of the plant.ylem cells are hard walled cells, which are stacked on top of each other and are mainly found in the center of the stem. Hence, xylem has another function, which is to provide mechanical support to the plant. Xylem is surrounded by the phloem. Phloem is the other type of transport tissue in vascular plants.
