What happens to a cell (plant cell or animal cell) when placed in this solution

What happens to a cell (plant cell or animal cell) when placed in the following solutions:

(a) Hypotonic solution

(b) Isotonic solution

(c) Hypertonic solution 

Answer:

(a) Hypotonic Solution: external solution is dilute i.e. high water concentration (low solute concentration). In this case water will rush into the cell and it will gain water. 

(b) Isotonic Solution: external solution concentration is same as internal solution

concentration of the cell. In this case, there is no net movement of water. 

(c) Hypertonic Solution: external solution is of high solute concentration i.e. low water concentration. Here water will rush out from cell and it will shrivel/shrink.
