Turgor Pressure and Plasmolysis
Captions available
The idea
Turgor pressure is cytoplasm pushing against a cell wall; plasmolysis is the membrane pulling away from that wall as water is lost.
In practice
A watered plant cell presses firmly against its wall, holding the plant upright; a wilted one's membrane has pulled inward.
Where people slip
A walled cell cannot lyse like an unwalled one — the wall limits the membrane's expansion.
