Plants have two systems for the transportation of substances-using two different types of transport tissue. Xylem transports water and solutes from the roots to the leaves, while phloem transports food from the leaves to the rest of the plant.Transpiration is the process by which water evaporates from the leaves, which results in more water being drawn up from the roots.ylem and phloem. Plants have two transport systems to move food, water and minerals through their roots, stems and leaves. These systems use continuous tubes called xylem and phloem, and together they are known as vascular bundles. Plant root. Plant root.
Water flow in xylem. 1  Uptake and transport of water with dissolved nutrients is essential for the life of plants. 2  Water moves through the plant body partly by diffusion, by osmosis across membranes, but mainly by bulk flow in the xylem in response to a pressure difference. The water status of a plant and water transport are evaluated by water potential, which is the sum of solute concentration (osmotic potential) and hydrostatic pressure (turgor), and to a smaller extent matrix potential.
