what is a xylem in a plant
Key Concepts: Xylem is the tissue of vascular plants that transports water and nutrients from the soil to the stems and leaves. Xylem plays an essential âsupportingâ role providing strength to tissues and organs, to maintain plant architecture and resistance to bending.hloem transports products of photosynthesis, primarily sucrose, from the leaves to the stem tissues and the roots. Xylem transport through sapwood moves water and nutrients from the roots to stems and leaves. Heartwood represents xylem that is no longer involved in transport.
