PLANT CELLS AND OSMOSIS
When water
enters a plant cell by osmosis the cytoplasm will swell but only until it
pushes against the cellulose cell wall. If water leaves a plant cell by osmosis
the cytoplasm will shrink but the cellulose cell wall will continue to give
support
Animal
cells have no cell wall, just a membrane. They are likely to suffer damage as a
result of osmosis. Animals have mechanisms to keep the blood plasma and the
body fluids at the same water potential and the cytoplasm of the cells.
