Contractile vacuoles in protists collect water and then expel it when they become full.
What else can I help you with?
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.
What types of vacuoles are found in protists?
Isolating materials that might be harmful or a threat to the cellContaining waste productsContaining water in plant cellsMaintaining internal hydrostatic pressure or turgor within the cellMaintaining an acidic internal pHContaining small moleculesExporting unwanted substances from the cellAllows plants to support structures such as leaves and flowers due to the pressure of the central vacuoleIn seeds, stored proteins needed for germination are kept in 'protein bodies', which are modified vacuoles.
What is the body cavity of protist?
Protists do not have a body cavity like more complex, multicellular organisms. They are unicellular or simple multicellular organisms that do not have specialized body cavities. Instead, they may have structures like vacuoles or contractile vacuoles that help with maintaining internal pressures and osmoregulation.
Why do protists need contractile vacuoles?
If the solution inside the amoeba is more concentrated than the outside, the water will diffuse into the cell through osmosis and eventually cause it to burst when there is way too much. The contractile vacuole prevents it from bursting by pumping water back out.
Where does a protist that contains contractile vacuoles live?
fresh water
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.
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.
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.
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.
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.

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.
