Question

The ___ is generated through osmotically driven inflow of water into cells across a selectively permeable membrane.


  1. Capilary pressure

  2. Turgor pressure

  3. Root pressure

  4. Transpiration pull


Solution

The correct option is B

Turgor pressure


Turgor pressure

Turgor pressure is well known in plant cells but can also occur in walled cells of other organisms. The turgor pressure in plants plays a key role in processes such as growth, development, mechanical support, signalling, flowering and stress response.

The ability to build up significant turgor pressure in cells has been key to the evolutionary success of terrestrial plants to pursue a sessile life strategy.
