gets to a plants cell by diffusion. Both stems and roots contain xylem vessels and phloem tubes. In a stem these are grouped into vascular bundles arranged in a ring. In a root these are arranged in the centre forming a structure called the stele. Xylem tissue has the dual functions of support and transport. It contains several different types of cells these are vessel elements‚ traceids‚ fibres and parenchyma cells. In contrast to this phloem tissue is living and comprises of sieve tubes‚ phloem
