Question

what will happen if,a cell is kept in isotonic solution​

Answer 1

If a cell is kept in an isotonic solution ; there would be no net movement as the concentration inside and outside the cell is same and already at equilibrium .

Supplementary information :

• Osmosis is the process by which water moves in or out of the selectively permeable membrane that is cell membrane. The rate of osmosis is dependent upon the substance dissolved.

• On the basis solute and solvent in a substance solutions are divided into three types :

1. Hypotonic solution
2. Hypertonic solution
3. Isotonic solution

• Hypotonic solution : The concentration of solute is more than a solvent that is the inside has more concentration than the outside. So , to attain equilibrium the solution will move out of the cell. Thus causing shrinkage in the cell.

• Hypertonic solution : The concentration of solute is less than the solvent that is the other side has more concentration than the inner side. So , to attain equilibrium the solution will move into the cell. Thus causing swelling in the cell.

• Isotonic solution : The concentration of solute and solvent is equal. So , there is no net movement.

Answer 2

Answer: A cell when kept in a Isotonic solution, will show no change....

Explanation:

Two solutions having the same osmotic pressure across a semipermeable membrane is referred to as an isotonic solution. It has the same osmolarity (solute concentration), as another solution. A solution is isotonic when its effective osmole concentration is the same as that of another solution. This state provides the free movement of water across the membrane without changing the concentration of solutes on either side. Some examples of isotonic solutions are 0.9% normal saline and lactated ringers.
