WebIn Amoeba, contractile vacuoles also collect waste produced by the cell. Summary: Vacuole Definition A vacuole is an organelle that is found in many types of cells, including animal, plant, fungi, bacteria, and protist cells. The contractile vacuole acts as part of a protective mechanism that prevents the cell from absorbing too much water and possibly lysing (rupturing) through excessive internal pressure. The contractile vacuole, as its name suggests, expels water out of the cell by contracting. See more A contractile vacuole (CV) is a sub-cellular structure (organelle) involved in osmoregulation. It is found predominantly in protists and in unicellular algae. It was previously known as pulsatile or pulsating vacuole.
