Turgor Pressure
The force that causes turgor pressure is osmosis.
A plant wilts when it has a decreased turgor pressure.
When the turgor pressure is low in a plant it will start to slouch and wilt.
Skin turgor is a qualitative assessment of how well hydrated the skin is. Good skin turgor is an indicator of adequate hydration, while poor skin turgor may indicate dehydration.
The plasma membrane is the structure associated with resisting turgor pressure.
Osmotic pressure across the cell wall, here called Turgor Pressure.
more solutes = less osmotic pressure = decreased turgor pressure
Plant cells are not known to have negative turgor pressure values. However, there are times when plants will have low turgor pressures which may result into negative turgor pressure values.
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.
When flowers lose their turgor pressure, or dry out they become wilted. If you remember to water them, flowers have abundant turgor pressure, and they will stay stiff, but if they become dry, or you forget to water them, they will lose their turgor pressure and begin to wilt.
