contractile vacuole

It has two contractile vacuoles, one at each end of the body.

A contractile vacuole, often quite large, is located in the posterior.

The number of contractile vacuoles varies from one, to many, depending on species.

Appears dark at lower powers because of dark structures near the contractile vacuole.

The nucleus is centrally located and there may be 4 to 8 contractile vacuoles.

Multiple contractile vacuoles lie in a row along the dorsal surface.

Contractile vacuoles found at near the bases of flagella.

There are two to several contractile vacuoles.

A contractile vacuole and anal aperture are in the posterior of the cell.

Like most other protists, amoebae have a contractile vacuole.

Amoebas have a contractile vacuole to expel excess water.

Organelles called contractile vacuoles forcibly expel excess water from the cell.

As in many freshwater protozoans, Stentor has a contractile vacuole.

The contractile vacuole expands and eventually discharges the water it contains to the exterior through the cell membrane.

A few contractile vacuoles around the periphery of the cell expel excess water, and are visible as clear bulges when full.

To counter this, water is secreted into a contractile vacuole as fast as it enters the amoeba.

Some cells, most notably Amoeba, have contractile vacuoles, which can pump water out of the cell if there is too much water.

Acidocalcisomes have been implied to work alongside the contractile vacuole in responding to osmotic stress.

Some protists accomplish this using contractile vacuoles, while freshwater fish excrete excess water via the kidney.

The oral cavity is apical and funnel shaped, with a contractile vacuole discharging directly into it.

Many protozoa have contractile vacuoles, which are vacuoles that can fuse or pinch off from the outer membrane.

Usually only the macronucleus and sometimes cilia and contractile vacuoles are visible in the cyst.

The contractile vacuole should not be confused with the vacuole, a different organelle much more common than the CV.

Contractile vacuoles are found in certain protists, especially those in Phylum Ciliophora.

It has a large posterior contractile vacuole, and a characteristic posterior indentation (more pronounced in underfed individuals).
