AnsweR :-
➡The Pressure Flow Hypothesis is also known as the Mass Flow Hypothesis.It was proposed by Ernst Munch, a German plant physiologist in 1930.
➡This Flow Hypothesis is the best-supported theory to explain the movement of sap through the phloem.
➡The high concentration of organic substances, particularly sugar and Many More Substance screates a diffusion gradient that draws water into the cells from the adjacent xylem. This creates turgor pressure, also known as hydrostatic pressure, in the phloem.
