WebContractile vacuole controls the osmotic balance and assists in the removal of extra water from amoeba’s body. Contractile vacuole helps with waste excretion. Its function is to act as the cell’s pump for removing extra water and waste. The extra water is gathered in the vacuoles when it enters the cytoplasm of the cell. 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.
