(A) According to the $Munch$ $Hypothesis$ (Pressure Flow Hypothesis),the translocation of food occurs from the source to the sink. At the sink end,sucrose is actively transported out of the $sieve$ $tube$ elements into the sink cells (such as root cells or storage organs). Once inside the sink cells,the excess sugar is polymerized into starch. This conversion reduces the osmotic concentration within the sink cells,which facilitates the continuous flow of sap from the source to the sink.

In plants,polymerisation of excess sugar into starch takes place in the . . . . . . at the sink end.
