Phloem transport: A review of mechanisms and controls

WebXylem cells. The xylem is specialised to transport water up the stem of a plant and into the leaves. Xylem vessels are made up of a series of connected dead xylem cells. The end walls of the dead cells are broken to allow water to move through. A substance called lignin strengthens the cell walls of xylem cells. WebThe diagram provided shows an outline of a phloem vessel. How are companion cells adapted for their role of actively transporting substances in and out of the sieve tube members?
