WebMunch hypothesis is based on the movement of phloem sap along a turgor pressure gradient. The mass flow of organic solutes takes place from the site of higher concentration, (source) to the site of lower concentration (sink). WebMass flow or bulk flow of solutes in sieve elements was initially suggested through the German Researcher Munch (1931). Munch visualises a pumping action in mesophyll cells.
