Vedclass · Answer

(D) The girdling experiment involves removing a ring of bark (phloem) from the stem of a plant. Since the phloem is responsible for the translocation of organic food (sucrose) from the leaves to the roots,removing this tissue blocks the downward movement of food. As a result,the portion of the stem above the girdle swells due to the accumulation of food,while the roots eventually die due to a lack of nutrients. Therefore,this experiment proves that phloem is the tissue responsible for the downward translocation of food in plants.
