Vedclass · Answer

(D) : In girdling or ringing experiments,a ring of bark is cut from the stem. This process removes the phloem. Nutrients accumulate above the ring,causing the bark to swell and potentially produce adventitious roots. Growth is vigorous above the ring. The tissues below the ring show a cessation of growth and begin to shrivel. The roots are starved of nutrients and die if the ring is not healed. The death of the roots eventually leads to the death of the entire plant,which demonstrates that the bark or phloem is responsible for the transport of organic solutes toward the roots.
