Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When the solute concentration outside a cell is the same as the concentration inside the cell, the solution is called ____
A
Hypertonic
B
Hypotonic
C
Isotonic
D
Unitonic
Explanation: 

Detailed explanation-1: -A cell placed into a hypertonic solution will shrivel and die by a process known as plasmolysis. An isotonic solution is any external solution that has the same solute concentration and water concentration compared to body fluids. In an isotonic solution, no net movement of water will take place.

Detailed explanation-2: -If the concentration of solution inside the cell and outside the cell is same, there will be no net movement of water molecules. Such type of solution is called isotonic.

Detailed explanation-3: -A hypotonic solution means the environment outside of the cell has a lower concentration of dissolved material than the inside of the cell. If a cell is placed in a hypotonic solution, water will move into the cell. This causes the cell to swell, and it may even burst.
