With the help of well-labelled diagrams, describe the process of plasmolysis in plants, giving appropriate examples.
When a cell is kept in a hypertonic solution, the concentration of the solution outside the cell is more. The concentration gradient makes the water from the cells moves out by the process of exosmosis. The water is lost from the cytoplasm and the vacuole. As the water is lost from the cell the cell membrane of the plant cells shrinks away from its cell wall. This condition of the cell is called as plasmolysed.
(b) Explain what will happen to a plant cell if it is kept in a solution having higher water potential.
