Answer» Correct Answer - D Apoplast pathway consists of non-living parts of plant body `i.e.` cell walls and intercellular spaces. In apoplast pathway, water passes from root hair to xylem through the walls of inervening cells without crossing any membrane or cytoplasm. The pathway provides the least resistance to movement of water . However it is interrupted by the presence of impermeable ligno-suberin Casparian strips in the walls of endodermal cells. |
