Question

What happens when we place the blood cell in water (hypotonic solution)? Give reason.

Answer 1

Hint: There are two types of solution based on the presence of the amount of solute.
They are hypertonic solutions and hypotonic solutions.
Hypertonic solution: in the solution the concentration of the solute is too high then the solution is called hypertonic solution.
Hypotonic solution: in the solution the concentration of the solute is too low then the solution is called hypotonic solution.


Complete step by step answer:
-In the question it is given that a blood cell is placed in a hypotonic solution.
-Hypotonic solution means the concentration of the solute is too low.
-We know that the blood cell contains high concentrations of the solute in it.
-When we are going to keep the blood cell in a hypotonic solution, the water molecules which are present in the hypotonic solution enters into the blood cell through the process osmosis.
-Then osmosis continues means flow of water from hypotonic solution into the blood cell continues and the blood cell will expand and eventually it bursts due to the lack of cell wall in blood cells.

-Therefore the blood cell is going to burst when we are going to keep it in a hypotonic solution because of endosmosis.


Note: Osmosis is a process through which the solvent is going to move from lower concentration solution to higher concentration solution. Plants and trees take water from soil through osmosis only.
Endosmosis means movement of water or solvent from the solution to inside of the cell.
Exosmosis means movement of water or solvent from inside of the cell to outside of the cell when the cell is present in the solution.
