Question

If the cell membrane pulls away from the cell wall whenever the cell loses water what happens to the plant cell

Answer 1

A plant cell is placed in a hypertonic solution, the plant cell loses water and hence turgor pressure by plasmolysis: pressure decreases to the point where the protoplasm of the cell peels away from the cell wall, leaving gaps between the cell wall and the membrane and making the plant cellshrink and crumple.

The process in plant cells where the plasma membrane pulls away from the cell wall due to the loss of waterthrough osmosis. A protein channel in a cell membrane that opens or closes in response to a particular stimulus.
