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.
Below the centre of the organism you see the feeding opening. The cilia make a current to sweep in bacteria and other food particles. At the base of the feeding opening the food has been enclosed by a vacuole. Food vacuoles are used to transport the food through the cell.Star-shaped contractile vacuoles or water expelling vesicles are used to balance the amount of water in the cell.Two nuclei bear the genetic information.ood vacuoles and the water expelling vesicles are such organelles. Many ciliates have developed all kinds of very special organelles. Paramecium uses so-called trichocysts: tiny pointed filaments that can be fired at a predator when threatened.
