\nThe correct answer is B) Transport of water and solutes.
\n<\/section>\n
\nXylem is the primary tissue in vascular plants responsible for transporting water and dissolved mineral nutrients (solutes) from the roots upwards to the rest of the plant, including the leaves. If the xylem is mechanically blocked, this upward movement of both water and solutes will be significantly impaired.
\n<\/section>\n
\nPhloem is another vascular tissue responsible for transporting sugars (produced during photosynthesis) from the leaves to other parts of the plant. Gases are primarily exchanged through stomata on leaves and lenticels on stems, not transported through xylem or phloem in bulk flow. Therefore, blocking xylem specifically affects water and mineral transport.
