Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What will happen when a cell is placed in an isotonic solution?
A
The pressure inside the cell increases due to some water entering the cell
B
Animal cells shrink and shrivel
C
The cells remain their normal size and shape
D
The water will leave the cell
Explanation: 

Detailed explanation-1: -When a red blood cell is placed in an isotonic solution, there will be no net movement of water. Both the concentration of solute and water are equal both intracellularly and extracellularly; therefore, there will be no net movement of water towards the solution or the cell.

Detailed explanation-2: -If a cell is placed in an isotonic solution, the water potential and will be equal inside and outside of the cell.

Detailed explanation-3: -If the solution is isotonic to the eukaryotic cell, it means the concentration inside the cell is same as the solution present outside. There will not be any movement of water between the cell and the surrounding as the cell will remain in a state of equilibrium.
