They can be found in plants' roots, stems, and leaves.Cross-section of a plant stem, showing vascular bundles nearer to the edge, with the phloem onthe outside and the xylem on the insideThe xylem transports water and mineral salts from the roots up to other parts of the plant.The xylem, made up of dead xylem cells, transports water up the stem of a plant and into theleaves. Xylem cells are broken to allow water to move through.Phloem cellsPhloem transports sucrose and amino acids between the leaves and other parts of the plant.The phloem transports food products from the leaves
