Question

What is the difference between isotonic ,hypotonic and hypertonic solutions?

Answer 1

1. Isotonic Solution:- If the medium has exactly the same water concentration as the cell, there will be no net movement of water across the cell membrane. Such a solution is known as an isotonic solution. The water flow in this type of solution is zero.
2. Hypotonic solution:- A hypotonic solution that has a lower solute concentration in comparison to another solution. The cell will also have a higher osmotic pressure the tendency for water to move into a cell by osmosis than the solution surrounding it. This will cause fluid to move into the cell and the cell often appears bloated.
3. Hypertonic solution:- A hypertonic solution is a particular type of solution that has a greater concentration of solutes on the outside of a cell when compared with the inside of a cell.

Isotonic Solution	Hypotonic solution	Hypertonic solution
1. the medium has exactly the same water concentration as the cell	1. hypotonic solution that has a lower solute concentration in comparison to another solution.	1. A hypertonic solution is a particular type of solution that has a greater concentration of solutes on the outside of a cell
2. Show no effect on cells	2. Causes cells to swell	2. Causes cell to shrink
3. isotonic solution is not helpful in food preservation	3. hypotonic solution is not helpful in food preservation	3.hypertonic solution is helpful in food preservation
