in osmosis What happen in potato A and in potato B?

In osmosis, water will move from an area of higher concentration to an area of lower concentration. In potato A, if placed in a hypertonic solution (higher solute concentration), water will move out of the potato causing it to shrink (plasmolysis). In potato B, if placed in a hypotonic solution (lower solute concentration), water will move into the potato causing it to swell (turgor pressure).
