Look at the shape of red blood cell in the given picture. In which of the following solution this cell must have been kept?

The correct answer is: Hypertonic

• The cells shrink when it is kept in a hypertonic solution.
• The concentration of solute will be more and water concentration will be less in a hypertonic solution.
• When the cells are kept in a hypertonic solution, the water from inside the cell will move to the external of cells by simple diffusion.
• This leads the cells to become shrink. The process is known as plasmolysis.
