The pressure flow theory states that water with food molecules inside of it moves through the phloem of a plant through pressure. This theory is meant to explain how food moves around inside plants. The pressure flow theory notes that pressure is created through water being pulled into the cells of the plant.
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.

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.
This video explains the pressure flow hypothesis, an explanation for how sugars are transported through the vascular tissue of a plant.
Slender-body theory is a methodology used in Stokes flow problems to estimate the force on, or flow field around, a long slender object in a viscous fluid. The shallow-water equations can be used to describe a layer of relatively inviscid fluid with a free surface , in which surface gradients are small.
Other articles where Pressure-flow hypothesis is discussed: angiosperm: Process of phloem transport: 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 ...
Pressure vs Flow, what is the difference between both? What is the relationship between Pressure and Flow? Flow is the rate at which fluid passes through a gives surface and it is caused by the difference in pressure within a fluid.
To understand the relationship between the pressure drop across a pipeline and the flow rate through that pipeline, we need to go back to one of the most important fundamental laws that governs the flow of fluid in a pipe: the Conservation of Energy, which for incompressible liquids, can be expressed using the Bernoulli Equation.
