When the concentration of solute inside and outside a cell is the same, the cell has reached?

           When the concentration of solute inside and outside a cell is the same, the cell has reached isotonic condition".

Explanation:

                   In isotonic condition the osmolarity of solute in and outside cell is same, therefore no net flow of water occurs. Semipermeable membrane ha a key role in maintaining isotonic condition in and outside the cell because this membrane allow the movement of water but prevent the entry of other molecules.
