Question

Which of the following is appropriate for mass flow hypothesis?

• A. Large amount of ions are also absorbed alongwith absorption of water.
• B. As suction pressure increases, absorption of water increases and along with water, absorption of ions also increases.
• C. Transpiration pull is responsible for absorption of ions.
• D. All the above.

Answer 1

Answer: (D)

All the above.

Mass flow hypothesis is also known as the pressure flow hypothesis. It was proposed by Ernst Munch in 1930.

During this process, the large number of ions are absorbed along with the absorption of water. Due to an increase in suction pressure and transpiration pull, absorption of water and ions increases.

So the correct answer is 'All of the above'.
