A cell placed in dilute solution bursts up. Which kind of cell it is ?
Answers
if it is a plant cell it does not burst but if it is a animal cell it bursts
this phenomenon is based on the principle of OSMOSIS
basically the cell have more percentage of salts in them which creates a concentration gradient . so when you place the cell in concentration which is less than that of the concentration of salts in the cell the the water enters the cell his leads to the bursting of the cell if it is an animal cell but in plant it doesnot burst because of the presence of cell wall while creates an opposite pressure
Answer:
It is a kind of hypertonic cell, a cell which has more solute dissolved in it with respect to the surrounding solution. This leads to a net movement of water into the cell which eventually causes it to burst.
The solution is dilute and is termed a hypotonic solution with respect to the cell.
Explanation:
Concept of tonicity:
- Tonicity is defined as the capability of a solution to bring about a change in the volume or water content of a cell.
- The cell walls or plasma membranes of the cells are a type of semi-permeable membrane which allows selective passage of specific solutes and solvents.
- These membranes allow free passage of water molecules into or outside the cell while restricting the passage of the solute molecules.
Concept of osmotic pressure:
- Osmotic pressure is the pressure applied against the wall of a semi-permeable membrane to prevent water from flowing into the cell.
- A solution which will have greater parts of solvent will exert a higher osmotic pressure.
- Based on the osmotic pressure differences between the cell and its surrounding fluid, the net flow of water (or, solvent molecules) can occur.
Isotonic, Hypotonic, and, Hypertonic solutions and their effect on the cells:
A] Isotonic Solutions:
A solution is said to be isotonic in nature if the osmotic pressure on both sides of the cell, i.e., of the cytoplasm and the outside extracellular part, is the same.
No net flow of water occurs in such a case. This is the ideal case.
B] Hypertonic solutions:
A solution is said to be hypertonic with respect to the cell when the osmotic pressure of the solution is lower as compared to the cytoplasm of the cell.
In such a case, water moves out of the cell and comes into the solution and the cell shrinks. This process is also known as the plasmolysis of the cell.
C] Hypotonic solutions:
A cell is said to be hypotonic with respect to the cell when the osmotic pressure of the solution is higher as compared to the cytoplasm of the cell, i.e., the solution is more dilute.
In such a case, water moves into the cell and the cell swells up. If the solution is too hypotonic, the cell may burst to lead to hemolysis.
