Does amoeba have contractile vacuole?
No they do not have contractile vacuoles.
Does an amoeba have more than one contractile vacuole?
no they have only one contractile vacuole because of it's environment, soil or water. A paramecium has two contractile vacuoles.
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.
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.

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

Are contractile vacuoles found in animal or plant cells?
Contractile vacuoles are found in plant cells.
What do contractile vacuoles protists do?
Contractile vacuoles in protists collect water and then expel it when they become full.
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 vacuoles rid cells of extra water?
Contractile Vacuoles
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.
How does osmosis and diffusion work in amoeba?
Amoeba obtains oxygen via diffusion; it takes in water by osmosis, but I would think this is more of a problem, since Amoeba lives in a freshwater environment, and water is always entering by osmosis. Amoeba's problem is getting rid of that water, which it does by means of contractile vacuoles.
