Examples of cells that contain this contractile vacuole are amoeba, paramecium, and some types of algae. Some sponges (including amoebocytes, pinacocytes, and choanocytes), singled-celled fungi, and hydra also have contractile vacuoles.
The activity of the contractile vacoule would decrease. While in  the hypotonic solution, water was moving into the paramecium  because it had a higher solute concentration â¦ that the solution that  it was in and water follows solute.he paramecium contains a vacuole called a contractile vauole. By contracting rhythmically, this specialized vacuole pumps excess water out of the cell. the control of water c â¦ ontent within the cell is just one example of an important process known as homeostasis.
