how much does a potato chip grow in moler solutions?

Introduction.
Osmosis is the net movement of water between water molecules from a weaker solution to a stronger solution through a semi-permeable membrane.

Structure of a plant cell.

What happens when a plat cell is placed in a solution weaker then the solution in a cell?
Osmosis takes place. Water diffuses into the cytoplasm and vacuole through the selectively permeable membrane. When this happens the solution in the middle is more concentrated and the vacuole expands while the cytoplasm moves to the side.
What happens when a plant cell is placed in a solution that is stronger then that inside the plant cell?
Again osmosis takes place. Water diffuses out of the cytoplasm and vacuole through the selectively permeable cell membrane. First the cell shrinks slightly and becomes flaccid; then the cell membrane pulls away from the cell wall. This causes spaces between the cell membrane and the cell wall. The solution is less concentrated.
