WebThe Mass Flow Hypothesis is a theory that explains the movement of water and solutes from high to low concentration across a selectively permeable membrane. It states that the movement of water and solutes is driven by a concentration gradient, with the movement occurring from an area of high concentration to an area of low concentration.

Webof solutes through the phloem. Munch’s Mass Flow Hypothesis The mass flow or pressure theory was first proposed by Munch (1930) and later elaborated by Crafts (1938). According to this theory, organic solutes are translocated en masse through the sieve tubes from the source (leaves) to the storage sites (roots, fruits and tubers). fmls discount code

Ernst Munch, a German scientist and physiologist, proposed the theory. This theory explains how simple sugar (or highly concentrated organic sugar) is transported to other plant areas.
