Best Answer: A hypotonic solution is one in which the amount of solute(dissolved substance) is less than the amount of that solute in the cell. Water will flow from the solution into the cell.A hypertonic solution is one in which the amount of solute is more than the amount of that solute in the cell.Water will flow from the cell into the solution. An isotonic solution has an even amount of solute on both sides. Water will flow evenly between the solution and the cell.ypotonic is where the amount of solute is greater inside the cell than outside (low concentrated solution), hypertonic is where the amount of solute is greater outside the cell than inside (high concentrated solution), and isotonic is where the amount of solute is the same inside the cell and outside the cell.
