Protists have salt particles inside their cytoplasm. When they are in freshwater the concentration of salt particles inside is higher than outside... however when they are in salt water the concentration is equally spread... (diffusion) the contractile vacuole job is to remove excess water... but if its in saltwater.. there isn't a need because. Of the diffusion that takes place.
What else can I help you with?
What organelle allows free-living protists to expel extra?
The contractile vacuole allows free-living protists to expel extra water
The structure that keeps a Paramecium living in fresh water from swelling and bursting is called a?
contractile vacuole. It regulates the water content within the cell by pumping excess water out to prevent the cell from swelling and bursting in a hypotonic environment like freshwater.
What organelle allows free living protists to expel etra water?
The organelle that allows free-living protists to expel excess water is called the contractile vacuole. This structure collects excess water that enters the protist's body and then contracts to expel it, helping to maintain osmotic balance and prevent the cell from bursting in hypotonic environments. Contractile vacuoles are particularly important in freshwater protists, where water influx is constant.
What are 6 kingdoms of living things?
Eubacteria, Archea, Protist, Fungus/Fungi, Plants, Animals
What cell structure prevents lysis in many single celled protists living in a fresh water environment?
Contractile vacuole helps to prevent lysis in many single-celled protists by regulating the water content within the cell. It accumulates excess water and then expels it from the cell, helping to maintain the cell's osmotic balance in a fresh water environment.

What is the function of the contractile vocuole?
The contractile vacuole helps regulate the water content of a cell by collecting excess water and expelling it from the cell to maintain osmotic balance. It is particularly important in organisms living in freshwater environments to prevent them from bursting due to excess water uptake.
What is the function of the contractile vacuole in a protozoan?
Living in fresh water, a hypotonic environment, causes water to enter the cell of certain protists (protozoa ) and would lysis the cell unless there were a way to expel this water. This is what contractile vacuoles do. When the fill with enough water microfilament contraction expels the excess water from the vacuole and helps the cell maintain internal isotonicity.
Why does amoeba die when cyanide is added to its water?
Cyanide is a toxic acid or salt and is deadly to just about any carbon based human life form. When Cyanide is added to the water of an Amoeba it stops the contractile vacuole from working, the contractile vacuole is vital in the survival of the Amoeba, because without it the Amoeba would basically just explode with water and die. The contractile vacuole pumps away the excess water. But, when cyanide is added to the water like I said the contractile vacuole will malfunction and not work. This will in the end result in the death of the cell.... I hope that helped!! :)
What type of organisms have cells with very large vacuoles?
Plant cells typically have very large vacuoles that store water, nutrients, and waste products. Vacuoles in plant cells help maintain turgor pressure and provide structural support for the plant. Some protists, such as amoebas, also have large contractile vacuoles that help regulate water balance.
Is protist living or nonliving?
Living
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!
Are animal like protist living or nonliving?
Living offcourse.
