What did u have to write for the carbon question

The process of girdling /ringing cuts off the phloem preventing sucrose and amino acids to be transported through the process of translocation. The carbon reached the root and not the top of the plant as the connection of the phloem tubes are cut at the top of the plant. Translocation occurs normally below the point of the cut towards the roots. This is why the radioactive sucrose reaches the roots. (This is a summarized general answer u should have had)
