en.wikipedia.org/wiki/Pressure_Flow_Hypothesis

The Pressure Flow Hypothesis, also known as the Mass Flow Hypothesis, is the best-supported theory to explain the movement of sap through the phloem. It was proposed by Ernst Munch, a German plant physiologist in 1930.

Mass-flow hypotheses include the pressure-flow hypothesis, which states that flow into sieve tubes at source regions (places of photosynthesis or mobilization and exportation of storage products) raises the osmotic pressure in the sieve tube; removal of sugars from sieve tubes in sink regions—i.e ...

Pressure Flow Hypothesis. Now that we've covered sinks and sources, let's look at the pressure flow hypothesis. This model of how phloem works is based on the relationship between sinks and sources.

Biology: Pressure flow hypothesis. STUDY. PLAY. Terms in this set (...) pressure-flow hypothesis. a hypothesis that states that sugars are actively transported into sieve tubes through osmosis where pressure builds at the source and reduces at the sink causing the flow from source to sink.

The Pressure Flow Hypothesis, also known as the Mass Flow Hypothesis, is the best-supported theory to explain the movement of food through the phloem. [1] It was proposed by Ernst Münch, a German plant physiologist in 1930. [2] A high concentration of organic substance inside cells of the phloem at a source, such as a leaf, creates a diffusion gradient (osmotic gradient) that draws water into ...
