Why is that a Paramecium sp. which lives in the ocean does not possess a contractile vacuole where as a similar Paramecium sp. which lives in fresh water must have such a cytoplasm organelle?
Because salt water go's throught them instead of inside them so they dont kneed to expel salt water
Suppose the paramecium were placed in a container of sea water what would you observe?
Usually, the paramecium used in a study like this are freshwater. Because the water inside the paramecium has a lower salt concentration, it moves out and shrivels the paramecium up, drying it out.
What would happen to the paramecium if the water-expelling vesicle stopped working?
The paramecium would eventually die because the paramecium wouldn't get any water and without the water-expelling vesicle the paramecium can't get the water out without getting other bacterias while doing so.
Why is a contractile vacuole important to paramecium?
Water is constantly coming down it's concentrations gradient and osmotically entering the paramecium's cell. The cell would soon burst if there were not a way to offload much of this water, so contractile vacuoles do this job for the paramecium.
The paramecium and water mold are in the kingdom?
protista :)
How do ciliates deal with osmosis?
Some ciliates, like the paramecium, have contractile vacuoles that fill with water and then expel the water when they get full.

Where does paramecium grow?
the paramecium lives in pond water and creeks sometimes.

Does a fish use it tail to expel or propel itsefl through water?
expel

If a paramecium were to swim from a hypotonic environment to an isotonic one would the activity of its contractile vacuole increase or decrease?
The activity of the contractile vacoule would decrease. While in the hypotonic solution, water was moving into the paramecium because it had a higher solute concentration that the solution that it was in and water follows solute. So, the isotonic solution would contain the same solute concentration as the paramecium so there would be no net water movement. Therefore, the contractile vacoule would decrease in its activity because there would be no water entering or exiting the paramecium.
Where does ameba and paramecium live?
These are fresh water protists. Lakes, streams and ponds would harbor paramecium and amoebae.
What is an fact about a paramecium?
Paramecium have anal pores that emit waste into surrounding water. *HOped this helped!* LOL~ XD
What would happen to the paramecium if it did not have a contractile vacuole?
If a paramecium did not have a contractile vacuole or it did not work it would fill with water and lyse.
