(B) The translocation of organic substances like sugars through the phloem can be demonstrated by the process of 'ringing' or 'girdling' the stem.In this experiment,a ring of bark (including the phloem) is removed from the stem of a plant,while the xylem is left intact.Over time,it is observed that the portion of the stem above the ring swells due to the accumulation of organic solutes (sugars) that cannot move downwards because the phloem has been removed.This confirms that the phloem is the tissue responsible for the translocation of organic food materials.
