Question:

Explain the mass flow hypothesis of transport in phloem.

Answer:

Mass flow hypothesis is also known as the press flow hypothesis. It was proposed by Munch in 1930 and it is accepted as most scientific. It states that when there is a high concentration of sugar present in the source then a diffusion gradient gets created between the sugar source and the sugar shrink where the sugar is stored. As the pressure is involved and movement of substance takes place in bulk thus this is called Mass Flow hypothesis or Pressure Flow hypothesis.
