SpletVerified 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. SpletSubscribe. 821. 33K views 2 years ago.

SpletThe Mass flow hypothesis is also known as the pressure flow hypothesis. It describes the movement of sap through the phloem, proposed by the German physiologist Ernst Munch in 1930. Some amount of sucrose from the leaf (source) enters the companion cells through the plasmodesmata across the concentration gradient. SpletThe most commonly accepted hypothesis to explain the movement of sugars in phloem is the pressure flow model for phloem transport. This hypothesis accounts for several observations: Phloem is under pressure Translocation stops if the phloem tissue is killed Translocation proceeds in both directions simultaneously (but not within the same tube) Spletlearn about how phloem translocates based on the mass flow/ pressure flow hypothesis and how the Munch Model works. kristi gongloff millward johnstown pa

SpletThe Pressure Flow Hypothesis is also known as the Mass Flow Hypothesis. It is the most accepted theory of movement of food through phloem. it was proposed by Ernst Munch in 1930s. A high concentration of glucose in the cells of phloem at the source sets up osmotic gradient. This results in movement of water from xylem into phloem. 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 Münch, a German plant physiologist in 1930. A high concentration of organic substances, particularly sugar, inside cells of the phloem at a source, such as a leaf, creates a diffusion gradient (osmotic gradient) that draws water into the cells from the adjacent xylem. This creates turgor pressure, also known …
