WebVerified by Toppr. Munch's Mass Flow Hypothesis is the theory which explains the flow of food materials through the phloem from the concentration regions to lower concentration regions. The force is needed to move organic food materials downwards in the phloem. This is caused due to differences in osmotic potential. Web1 sept. 1981 · Abstract.

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. Based on Munch’s hypothesis, the sieve tubes are connected to each other by way of cytoplasmic connections, developing a continuous system known as symplast. ram 2500 diesel chirps when turningram 2500 diff coverWeb1 mar. 2024 · The Munch pressure and mass flow model is one of the commonly accepted hypotheses for describing the physics of sucrose transport in the phloem systems. ...
