Paramecia live in water so they don't need to "get" it except by sucking some in if they happen to need any.
the paramecium lives in pond water and creeks sometimes.
Freshwater is hypotonic to paramecium, which means it has a lower concentration of solutes compared to the inside of the paramecium. As a result, water enters the paramecium through osmosis, potentially causing it to swell. To regulate this influx of water and maintain osmotic balance, paramecium possess contractile vacuoles that expel excess water.
When a Paramecium gets close to salt, it will experience a process called osmosis. Salt has a higher concentration of solutes compared to the inside of the Paramecium, so water will move out of the Paramecium through osmosis to try to balance the concentration of solutes on both sides of the cell membrane. This loss of water can cause the Paramecium to shrink or even die if the salt concentration is too high.
The paramecium belongs to the kingdom Protista, while the water mold belongs to the kingdom Fungi.
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 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.
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.
The organism paramecium moves using hair-like structures called cilia that cover its entire body. The coordinated beating of these cilia allows the paramecium to propel itself through water by creating a flow of water around its body.
The paramecium has a stiffer cell membrane than the amoeba.
The paramecium would have difficulty regulating its water balance, leading to swelling and potential bursting from an influx of water. Without a contractile vacuole, the paramecium would struggle to expel excess water and maintain osmotic balance, ultimately leading to cell damage or death.
These are fresh water protists. Lakes, streams and ponds would harbor paramecium and amoebae.
Paramecium have anal pores that emit waste into surrounding water. *HOped this helped!* LOL~ XD
