Because their membranes are not selectively permeable and let water through. These vacuoles fill up with water in order to collect water and make sure the protists don't overflow and overfill with water and explode. After the vacuoles are full they release the water back into the environment.

What organelle helps remove excess water?
It is Contractile Vacoule. Contractile Vacoule, a structure that collects the extra water and then expels it from the cell.
How osmoregulation is carried out in a named protozoan?
Osmoregulation is a problem for fresh water Protozoa due to constant influx of water, which they expel by way of contractile vacuole , marine species are mostly osmoconformers .
What organelle is used to remove excess water from protozoa?
Contractile Vacuole
What organelle helps move excess water?
A specific type of vacuole, called a contractile vacuole expels excess water from many fresh water protists.
What organelles function in the maintenance of water balance in freshwater protozoa?
plasma membrane. it controls the water movement through osmosis.
What organelle helps remove excess water?
It is Contractile Vacoule. Contractile Vacoule, a structure that collects the extra water and then expels it from the cell.
A paramecium eliminates excess water by means of?
Contractile vacoule
Organelle that pumps water out of the cell?
The Contractile Vacoule.

Osmoregulation is a problem for fresh water Protozoa due to constant influx of water, which they expel by way of contractile vacuole , marine species are mostly osmoconformers .
What organelle is used to remove excess water from protozoa?
Contractile Vacuole
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.
What organelle helps move excess water?
A specific type of vacuole, called a contractile vacuole expels excess water from many fresh water protists.
Where does a protist that contains contractile vacuoles live?
fresh water
What organelles function in the maintenance of water balance in freshwater protozoa?
plasma membrane. it controls the water movement through osmosis.
Where does a protist with contractile vacuoles live?
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.
The structure that keeps a Paramecium living in fresh water from swelling and bursting is called a?
contractile vacuole
