Detailed explanation-1: -An isotonic solution is a solution in which the amount of dissolved material is equal both inside and outside of the cell. Water still flows in both directions, but an equal amount enters and leaves the cell.

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: -when both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of equbilrium .

Detailed explanation-4: -In an isotonic solution, the flow of water in and out of the cell is happening at the same rate. Figure 8.4.

Detailed explanation-5: -The end result is an equal concentration, or equilibrium, of molecules on both sides of the membrane. At equilibrium, movement of molecules does not stop. At equilibrium, there is equal movement of materials in both directions. Not everything can make it into your cells.
