If a cell is placed in an isotonic solution, how does the cell maintain homeostasis? What about in hypotonic and hypertonic solutions?

If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane.  When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
