Osmosis in plant cells can cause water to enter the cells or water to exit the cells. When water enters the cell it is called turgid. If a plant cell is placed in distilled water, because there is a low concentration of water in the cell, water from the outside enters through a semi-permeable membrane called the cell membrane. Causing the cell to become turgid because the cell sap pushes outwards on the cell. When water exits the cell, this happens because a lower concentration of water surrounds the cell, this causes the water in the cell sap to move out of the cell. This makes the cell flaccid (loose) because the vacuole...
