As the osmotic pressure of water, water going down it's concentration gradient, built up in the cell there would be increasing pressure on the cell membrane and without the vacuole to relieve this pressure the cell would burst.
To get rid of excess water which enters the body through osmosis
Yes. A euglena DOES have a contractile vacuole. It is used to maintain the organism's water balance by expelling excess water from the cytoplasm into the reservoir. :)
If a paramecium did not have a contractile vacuole or it did not work it would fill with water and lyse.
The contractile vacuole is the organelle of a protist that empties the fluid out of the cell, if this stops working, then the cell will eventually expand and burst, the scientific term for this is cytolysis :)
If the solution inside the amoeba is more concentrated than the outside, the water will diffuse into the cell through osmosis and eventually cause it to burst when there is way too much. The contractile vacuole prevents it from bursting by pumping water back out.
An Onion cell as a contractile vacuole. This allows the cells to remover more water especially when placed into a hypotonic solution. An epithelial skin cell of the cheek does not have a contractile vacuole. The acess water cannot be stored, therefore the cell bursts.
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!
If a paramecium did not have a contractile vacuole or it did not work it would fill with water and lyse.
i don't know sorry
The disadvantages of euglena are mostly related to its structure and the fact that there is a debate that never ends on whether it is a plant or animal. The lack of routine genetic analysis is the main disadvantage.
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.
The contractile vacuole should be active when the paramecium is in water. We learned in 6th grade science that a contractile vacuole pumps water out of the cell to prevent it from getting too much water by osmosis. Without working contractile vacuoles, the cell would get too big and might die!

The contractile vacuole removes the excess water that enters the organism through osmosis (passive transport doest not require ATP) down a concentration gradient. Because the water is more concentrated on the outside of the organism in the fresh water of its habitat the water enters the organism by osmosis. The water on the outside is hypertonic and the water on the inside of the organism is hypotonic. The contractile Vacuole acts as a pump to remove and excess water without this the cell would burst from to much excess water.
No, some single celled organisms, protists, generally, live in hypotonic solutions of fresh water and if they did not have a method to " bail " out this water their cell would burst. So the contractile vacuole, which has filament motive forces, fills with water and then contracts which squirts the water out of the cell.
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!! :)

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.
A lysosome combines with the vacuole and digests the enclosed solid material.
