Vedclass · Answer

(C) The ringing experiment (or girdling experiment) involves removing a ring of bark (including the phloem) from the stem of a woody plant.Since the phloem is responsible for the translocation of food (sucrose) from leaves to roots,the removal of this tissue causes food to accumulate above the ring,leading to swelling.Simultaneously,the xylem remains intact,allowing the ascent of sap (water and minerals) to continue to the upper parts of the plant.Therefore,this experiment demonstrates both the path of food translocation and the path of water transport.
