Most ciliates also have one or more prominent contractile vacuoles, which collect water and expel it from the cell to maintain osmotic pressure, or in some function to maintain ionic balance. And the contratile vacuoles pump out excess water. If a plant cell looks like a water balloon, the cell wall is analogous to a cardboard box that protects the balloon from damage.
