Vedclass · Answer

(B) The Munch hypothesis,also known as the Pressure-Flow Hypothesis,explains the translocation of sugars in plants.According to this theory,the flow of soluble substances (sucrose) occurs due to a pressure gradient.Photosynthesis in the leaves creates a high concentration of sucrose,which leads to high osmotic pressure and high turgor pressure.In contrast,the sink (roots or storage organs) has a lower concentration of sucrose,leading to lower turgor pressure.This difference in turgor pressure between the source and the sink causes the mass flow of sap through the phloem.

According to the Munch theory,the cause of the flow of soluble substances is
