Describe the Mass Flow Hypothesis for Translocation of Organic Solutes (Food) In Plants

Answer:

Munch’s Mass Flow Hypothesis is the theory that describes the movement of food materials from the concentration areas to lesser concentration areas via the phloem. It takes force to transfer organic food materials in the phloem downwards. This is caused by varying osmotic ability. In between supplying and receiving tissues, there is a turgor pressure gradient. The experiment was conducted utilizing two osmometers having different concentration. This theory shows that food is moving from the leaves to the roots. The leaves are the regions that grow the food and thus act as the source end. The roots are those regions that allow food to absorb and breathe. And the roots act as an end to the drain. The flow is from the end of the source to end of the sink.
