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.
In Paramecium, which has one of the most complex contractile vacuoles, the vacuole is surrounded by several canals, which absorb water by osmosis from the cytoplasm. After the canals fill with water, the water is pumped into the vacuole.he contraction of the contractile vacuole and the expulsion of water out of the cell is called systole. Water always flows first from outside the cell into the cytoplasm, and is only then moved from the cytoplasm into the contractile vacuole for expulsion.
