A hypotonic solution is any solution that has a lower osmotic pressure than another solution. In the biological fields, this generally refers to a solution that has less solute and more water than another solution.
In a hypotonic solution the total molar concentration of all dissolved solute particles is less than that of another solution or less than that of a cell.

Explanation:
The external solution having less concentration than the cell sap is called a hypotonic solution.
Hypotonic Solution:
A hypotonic solution is a solution that has a lower solute concentration compared to the cell sap or the solution inside the cell. In other words, the concentration of solutes is higher inside the cell than in the external solution.
Effects of a Hypotonic Solution on Cells:
When a cell is placed in a hypotonic solution, water molecules move from the solution into the cell through the process of osmosis. This is because water moves from an area of lower solute concentration (the hypotonic solution) to an area of higher solute concentration (inside the cell). As a result, the cell swells and may eventually burst.
Examples of Hypotonic Solutions:
- Distilled water is a common example of a hypotonic solution as it has a very low concentration of solutes.
- Another example is a solution with a lower concentration of salt compared to the cytoplasm of red blood cells. When red blood cells are placed in a hypotonic solution, they may undergo hemolysis, which is the bursting of the cells.
Importance of Hypotonic Solutions:
Hypotonic solutions have important applications in various fields, including biology and medicine. They are used in processes like cell culture, where cells need to be kept in a hypotonic environment to prevent dehydration and maintain their functionality.
In conclusion, a hypotonic solution is an external solution that has a lower concentration of solutes compared to the cell sap. When a cell is placed in a hypotonic solution, water moves into the cell through osmosis, causing the cell to swell.
