Pressure flow hypothesis

Vedclass · Answer

(D) The $Pressure \ flow \ hypothesis$ (also known as the $Munch \ hypothesis$ or $Mass \ flow \ hypothesis$) is the most widely accepted theory to explain the translocation of organic solutes (sugars) from the source (leaves) to the sink (roots,fruits,or storage organs) over long distances in plants.According to this theory,glucose produced in the leaves is converted into sucrose,which is then loaded into the phloem sieve tube cells. This creates a high osmotic pressure,causing water to enter from the adjacent xylem,resulting in a high turgor pressure. The sap then moves towards the sink,where the pressure is lower,facilitating the bulk flow of nutrients.
