Contractile vacuoles are organelles in some single-celled organisms that help regulate water balance by contracting rhythmically to expel excess water from the cell. This process prevents swelling and disruption of cellular functions due to osmotic changes.
Contractile vacuole plays a part in osomoregulation. It stores excess water that enters the cell and after a stage expells it to the exterior.
The Contractive Vacuole Contains Most New Proteins For The Cell. The Contractive Vacuole Is An Importnant Organelle Because When The Cell Has No Proteins It Refers To The Contravtive Vacuole.
It's like the kidney of a cell; Pumps excess water out of a cell
The role of a contractile vacuole is osmoregulation. This will store up excess water in the cell and expel it when needed and therefore creating a balance in the cell.

Where does a protist with contractile vacuoles live?
Contractile vacuoles in protists collect water and then expel it when they become full.
Are contractile vacuoles found in animal or plant cells?
Contractile vacuoles are primarily found in single-celled organisms, such as protists, that live in freshwater environments. They help regulate the water content of the cell by pumping out excess water to prevent it from bursting. Neither animal nor plant cells typically possess contractile vacuoles.
Which protists are contractile vacuoles easy to see?
Contractile vacuoles are commonly found in freshwater protists, such as amoebas and paramecia. These organisms live in hypotonic environments and use contractile vacuoles to regulate their water balance by expelling excess water to prevent bursting.
Organelles that collect excess water inside the cell and force water out are called?
The organelles that collect excess water inside the cell and force it out are called contractile vacuoles. It is primarily involved in osmoregulation and is usually found in protists and unicellular algae.
Why contractile vacuoles would be of little value to one cell organisms living in the ocean?
I do get it,for the organism living in the hypertonic salt water(ocean) the contractile vacuole is most not needed since the water in the organism are already on thier way out!
Where contractile vacuoles are located in amoeba?
contractile vacuoles merge with the cell membrane..
What do contractile vacuoles protists do?
Contractile vacuoles in protists collect water and then expel it when they become full.
How are contractile vacuoles different then types of vacuoles?
Contractile vacuoles are formed when a food particle is engulfed. Their size depends on the size of food particle. They are not predefined. Other vacoules are predefined and exist whether the food particles are present in them or not.
Why are contractile vacuoles surrounded by mitochondria?
Contractile vacuoles are responsible for regulating osmotic balance in unicellular organisms by expelling excess water. Having mitochondria surrounding the contractile vacuoles helps provide the necessary energy (in the form of ATP) for the vacuoles to pump out water efficiently. This ensures proper functioning of the contractile vacuoles in maintaining cellular homeostasis.
Where does a protist with contractile vacuoles live?
Contractile vacuoles in protists collect water and then expel it when they become full.
Are contractile vacuoles found in animal or plant cells?
Contractile vacuoles are primarily found in single-celled organisms, such as protists, that live in freshwater environments. They help regulate the water content of the cell by pumping out excess water to prevent it from bursting. Neither animal nor plant cells typically possess contractile vacuoles.
What do vacuoles in protists do?
Contractile vacuoles in protists collect water and then expel it when they become full.
Marine protoza do not have contractile vacule?
That's correct, marine protozoa do not have contractile vacuoles. Contractile vacuoles are typically found in freshwater protozoa and serve to regulate water balance by expelling excess water from the cell. Marine protozoa have adaptations to maintain water balance in a high-salt environment without the need for contractile vacuoles.
How are contractile vacuoles different from types of vacuoles?
Contractile vacuoles are formed when a food particle is engulfed. Their size depends on the size of food particle. They are not predefined. Other vacoules are predefined and exist whether the food particles are present in them or not.
Where does a protist that contains contractile vacuoles live?
fresh water
What is the process that cause water to flow into contractile vacuoles?
Osmosis .
Why do amoebae and paramecia require contractile vacuoles?
Amoebae and paramecia require contractile vacuoles for osmoregulation. This is a process which gives these organisms that live in fresh water ability to regulate water balance.
