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.
Parenchyma is an example of a simple tissue (composed only of parenchyma cells); xylem is an example of a complex tissue (composed of tracheids, vessel members, parenchyma cells, and sometimes fibers). Tissues are organized into three tissue systems: the dermal, vascular, and ground systems.ROCEDURE: Cells and Tissues of the Plant (Angiosperm) Body The vascular plant sporophyte is usually composed of three kinds of vegetative organs: stems, leaves, and roots. In this lab, you will learn about the various cells and tissues that make up these organs.
