Contractile Vacuole Definitions

  1. In protists and some animals, a clear fluid-filled vacuole that takes up water from within the cell and then contracts, releasing it to the outside through a pore in a cyclical manner. It functions primarily in osmoregulation and excretion.

Contractile Vacuole Explanation

Contractile vacuole is an organelle that is involved in the process of osmoregulation. It is usually found in unicellular algae and protists. It was formerly known as pulsating vacuole or pulsating. It regulates the water's quantity inside a cell. In the freshwater environment, hypotonic is the concentration of solutes, which means that means higher inside the cell than the outside environment.
