Want this question answered?
you can soak it in a high concentration of salt water which causes it to lose its turgor pressure ,therefore it shrinks in size by diffusional water from inside the potato moves to the salt solution)
They all have to do with the salt to water ratio of a cell.
more solutes = less osmotic pressure = decreased turgor pressure
Turgor would be lost when a plant loses water. Salt water can cause water to move out of plant cells and the plant would wilt.
The absorbed water will go to the central vacuole, giving the cell more turgor pressure.
Turgor Pressure
Animals with very little body fat will appear to be more dehydrated that they actually are when the skin turgor test is used.
Turgor pressure is usually calculated as the difference between water potential and osmotic potential. In herbaceous plants turgor pressure is almost solely responsible for maintaining an erect habit. Wilting of leaves is due to loss of turgor in the leaf.
The force that causes turgor pressure is osmosis.
A plant wilts when it has a decreased turgor pressure.
Absorbs more water by endoosmosis
When the turgor pressure is low in a plant it will start to slouch and wilt.
