Vedclass · Answer

(C) The translocation of organic solutes (sugars) in plants occurs through the phloem. The most widely accepted theory to explain this process is the $Mass \ flow \ hypothesis$ (also known as the $Pressure \ flow \ hypothesis$),proposed by $Ernst \ Munch$. According to this theory,glucose produced in the leaves (source) is converted into sucrose and loaded into the phloem,creating a high osmotic pressure. This causes water to enter from the xylem,generating a pressure gradient that pushes the sap towards the sink (roots or storage organs).

Which theory best explains the translocation of organic solutes?
