Xylem and Phloem are found in the vascular tissue system in plant organisms. The xylem transports the mineral icons from the root to the rest of the plant, and the phloem carr â¦ ies the sugar and various other nutrients throughout the plant.ylem: tubes that brings water and minerals from the roots into the leaf. Phloem: tubes that usually move sap, with dissolved sucrose, produced by photosynthesis in the leaf, out of the leaf and to other parts of the plant.
