CONTRACTILE VACUOLE

This article appears in Volume V07, Page 40 of the Encyclopedia Britannica.

Encyclopedia Britannica - Main :: COM-COR
CONTRACTILE VACUOLE , in
biology
 , a spherical space filled with liquid, which at intervals discharges into the
medium
 ; it is found in all fresh-water groups of Protozoa, and some marine forms, also in the naked aquatic reproductive cells of Algae and Fungi. It is absent in states with a distinct cell-
wall
  to resist excessive turgescence, such as would lead to the rupture of a naked cell, and we conclude that its
chief
 
function
  is to prevent such turgescence in unprotected naked cells. It fulfils also
respiratory
  and renal functions, and is comparable, physiologically, to the contractile vesicle or bladder of Rotifers and Turbellarians. In many species it is
part
  of a complex of canals or spaces in the protoplasm.
See M. Hartog, British Association Reports, and Degen, Botanische Zeitung, vol. lxiii. Abt. I (1905) (see also PROTOZOA; PROTOPLASM).
