What else can I help you with?
Does amoeba have contractile vacuole?
Yes, many species of amoeba have a contractile vacuole that helps regulate water content within the cell by expelling excess water to prevent bursting due to osmotic pressure.
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.
How are the vacuoles from paramecia different from the vacuoles of other organisms?
The paramecium might have a contractile vacuole, whereas cells like animal and plants just have a normal one.
Why would you expect a freshwater amoeba to be more likely to have contractile vacuoles than a marine amoeba?
Because the surrounding freshwater concentration is higher than the salt concentration inside and so all the water from the vacuoles has left because of osomosis. while the marine amoeba has the surrounding salt concentration equal to the concentration inside the vacuole.
Why would you expect a freshwater amoeba to be more likely to ha contractile vacuoles than marine amoeba would?
Marine amoebae live in a saltwater environment. If the vacuoles take in too much salt, it'll suck all the liquidy stuff out of the amoeba itself. Freshwater amoebae are in a freshwater environment so they don't have to worry about that.

What is the contractile vacuoles physiological function in amoeba and paramecia?
They have an excretory function.They remove excess water from cells.

What do contractile vacuoles protists do?
Contractile vacuoles in protists collect water and then expel it when they become full.

What controls the water content in an amoeba?
In an amoeba, the water content is controlled by the contractile vacuole. It fills with water (entering the amoeba by osmosis) and then empites the water once it reaches a certain level. If water was not displaced by the contractile vacuole, then the amoeba would burst.
What parts of the cell store water and maintain its rigidity?
Vacuoles. Vacuoles store food and waste. Some vacuoles store extra water. They are often described as liquid filled space and are surrounded by a membrane. Some cells, most notably Amoeba, have contractile vacuoles, which can pump water out of the cell if there is too much water.
What organelles are found in an amoeba?
An amoeba contains several organelles, including a nucleus, mitochondria for energy production, golgi apparatus for packaging and transporting proteins, and vacuoles for storing nutrients and expelling waste. Some amoebas also have specialized organelles like contractile vacuoles for osmoregulation.
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.
