Vedclass · Answer

(B) According to the $Munch$ Pressure-Flow Hypothesis,the translocation of food occurs from the source (leaves) to the sink (roots/storage organs). At the source,sugar is loaded into the phloem,creating a high osmotic pressure that draws water from the adjacent xylem. At the sink end,sugar is actively removed from the phloem to be used by the cells for metabolism or storage. As the sugar concentration decreases,the osmotic pressure drops,causing the excess water to move out of the phloem and return to the xylem. Therefore,the correct option is $B$.
