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 is the function of the contractile vacuole?
The contractile vacuole functions as a water regulatory organelle in freshwater protists by collecting excess water and expelling it from the cell. Its primary role is to maintain the cell's internal environment by preventing it from swelling and potentially bursting due to excess water intake.
What is the function of a permanent vacuole?
The function of a permanent vacuole in plant cells is to store water, nutrients, and waste products. It also helps to maintain turgor pressure within the cell, which provides structural support to the plant.
What protozoan has pseudopods?
The amoeba has pseudopods.
Are protozoan capable of asexual or sexual reproduction?
Asexual
What is the protozoan which constantly changes shape as it moves?
amoeba
What organelle helps move excess water?
A specific type of vacuole, called a contractile vacuole expels excess water from many fresh water protists.
Who has contractile vacuole amoeba or paramecium?
paramecium has the contractile vacuole yooo!
What has a contractile properties?
a contractile vacuole
Organelle that pumps water out of the cell?
The Contractile Vacoule.
What structure expels excess water in the amoeba?
The contractile vacuole is the structure in amoeba responsible for expelling excess water and maintaining osmotic balance within the cell. It collects and removes the excess water by contracting and expelling it out of the cell.
What is the function of the contractible vacuole in the Euglena?
Contractile vacuoles are found in aquatic protists.They remove excess water.
How does the contractil e vacuole help freshwater organisms survive?
The contractile vacuole in freshwater organisms helps regulate the water balance within the cell by periodically contracting to expel excess water that diffuses into the cell from the hypotonic environment. This prevents the cell from bursting due to osmotic pressure and helps maintain cellular homeostasis.
Some protozoans have special organelles called contractile vacuoles that continually eliminate excess water from the cell The presence of these organelles tells you that the environment?
is hypotonic, meaning that there is more water outside the cell than inside. The contractile vacuole helps the protozoan maintain osmotic balance by expelling the excess water that enters the cell through osmosis.
Excess water is removed by what kind of vacuole?
contractile vacuole
Does an amoeba have more than one contractile vacuole?
No, an amoeba typically has one contractile vacuole, which is responsible for expelling excess water and waste from the cell. The contractile vacuole helps to regulate the osmotic balance of the cell by maintaining the proper water content.
What is the function of a cell in single celled organisms?
The function of contractile vacuole is to store excess of water that enters the single-celled organism and then expel it to the exterior
What is the function of a contractile vacuole in some in some single-celled organisms?
Vacuoles can store many types of molecules, in particular essential substances that are potentially harmful if present in bulk in the cytoplasm The contractile vacuole stores excess water that enters into it and expels it out after a stage
