A contractile vacuole (CV) is a sub-cellular structure (organelle) involved in osmoregulation. It is found predominantly in protists and in unicellular...

its structure varies according to the requirements of the cell. Contractile vacuoles ("stars") were first observed by Spallanzani (1776) in protozoa,...

Without a contractile vacuole, the cell would fill with excess water and, eventually, burst. Marine amoebae do not usually possess a contractile vacuole because...
