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.
