A plant cell placed in a concentrated solution
-When a plant cell is placed in a concentrated solution, then water moves out of the plant cell by osmosis as there is a more concentrated solution outside the cell.
-As the water moves out, the vacuole and cytoplasm shrink and the membrane pulls away from the cell. This is called plasmolysis and the cell is described as plasmolysed. This kills the cell as the membrane is damaged.
-The gaps are filled with the external solution. Since the cell wall is fully permeable to the external solution it moves through the wall and occupies the space
