Question

Munch hypothesis is based on translocation of food due to

• A. Imbibition force
• B. Turgor pressure (TP) gradient
• C. Both A and B
• D. None of these

Answer 1

The correct option is B Turgor pressure (TP) gradient

Munch hypothesis is also called the pressure flow hypothesis, it explains the movement of sap through the phloem. It proposed by Ernest Munch in 1930. High concentration of organic substance inside the cell of the cells of the phloem at a source that creates the diffusion gradient drawing water from the adjacent xylem resulting into the turgor pressure.

So, the correct answer is 'Turgor pressure gradient'.
