Which of the following is not correct with respect to the mass flow h...
Explanation:
Mass flow hypothesis is a widely accepted hypothesis that describes the mechanism of sugar transport in plants through phloem tissue.
The correct statement regarding the mass flow hypothesis is:
- Loading of phloem sets up a water potential gradient that facilitates the mass movement in phloem.
- The sugar which is transported in phloem sieve.
- The sugar is moved bidirectionally.
The incorrect statement regarding the mass flow hypothesis is:
- As hydrostatic pressure in phloem sieve tube increases, pressure flow stops and sap accumulates in the phloem.
This statement is incorrect because as the hydrostatic pressure in the phloem sieve tube increases, the pressure flow continues and the sap moves towards the sink. The pressure flow is maintained by the continuous loading of sugar at the source and unloading at the sink.
In summary, the mass flow hypothesis describes the mechanism of sugar transport in plants through phloem tissue. It involves the loading of sugar at the source, setting up a water potential gradient, and maintaining pressure flow towards the sink.

The movement of sugars in the phloem begins at the source, where sugars are loaded (actively transported) into a sieve tube.
Loading of the phloem sets up a water potential gradient that facilitates the mass movement in the phloem.
Phloem tissue is composed of sieve tube cells, which form long columns with holes in their end walls called sieve plates. Cytoplasmic strands pass through the holes in the sieve plates, so forming continuous filaments. As hydrostatic pressure in the sieve tube of phloem increases, pressure flow begins, and the sap moves through the phloem.
