WebMar 28, 2024 · Xylem and phloem give vascular plants their classification; they are the vascular tissues that transport substances throughout the plant. Function of Xylem The main function of xylem is to transport water, and some soluble nutrients including minerals and inorganic ions, upwards from the roots to the rest of the plant. WebThis creates a hypertonic condition in the phloem. Water in xylem vessels adjacent to phloem moves through endosmosis. Osmotic pressure rises and phloem SAP moves from an area of higher osmotic pressure to the area of low pressure. Osmotic pressure is maintained low at the sink.
