They work to maintain a solvent/solute balance in the cell through a … The contractile vacuole, as its name suggests, expels water out of the cell by contracting. The growth (water gathering) and contraction (water expulsion) of the contractile vacuole are periodical. One cycle takes several seconds, depending on the species and the osmolarity of the environment. The stage in which … 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. See more The contractile vacuole is a specialized type of vacuole that regulates the quantity of water inside a cell. In freshwater environments, the See more The CV does not exist in higher organisms, but some of its unique characteristics are used by them in their osmoregulatory mechanisms. Research on the CV can therefore help us understand how osmoregulation works in all species. Many … See more The way in which water enters the CV had been a mystery for many years, but several discoveries since the 1990s have improved … See more
