These contractile vacuoles are amazing. My students are so amazed, they are all keeping the link to this and showing their parents for extra credit.
what are other bodies moving in the side of paramecium
In Paramecium, which has one of the most complex contractile vacuoles, the vacuole is surrounded by several canals, which absorb water by osmosis from the cytoplasm. After the canals fill with water, the water is pumped into the vacuole

This is for non-salty-water right? I wonder what would happen if it was an isotonic environment.
Is this an active transport or passive transport?!?!
Thanks
@@sarias3896 probably passive since it takes place by Osmosis
I love watching contractile vacuoles. Could watch for hours. My favorite is when Phil bumped into Eugene, that was funny.
WOW! Excellent time-lapse!
I don't think it's a time lapse. According to Wikipedia the expansion and contraction cycles are every few seconds!
what are other bodies moving in the side of paramecium
that is the most beautiful thing I've ever seen
which part of the movement does the pumping occur? is it when the vacuoles' center seemingly gone or the other way around?
Cống hiến hơn nữa trong sự nghiệp của mình. Một lần nữa cảm ơn Đức Phúc và chương trình đã mang đến những giây phút thư giãn này. Mãi yêu!!!❤❤❤
What is the magnification used in the first and second half of the video?
Wow amazing !!!
What type of the microscope and magnification use Bro ?
Beautiful.
I got someone who commented only 6 days ago 😅😅
I LOVE CONTRACTILE VACOULES
God is wonderful
what are those small orgs swimming around the paramecium
Very nice
They’re so cute 😄🦦
I LIKE IT
Excellent

Other Paramecium goes "Oops!" *Scurries off in other direction*
Cute.
Just observed this and wanted to confirm what was going on. Great video!
Also, what are those black lines?
The black lines might be imperfections on the slide itself so disregard. The observation here is a water pump on the bacteria (called a contractile vacuole) that controls the regulation of water inside of the paramecium. Without the pump, the organism can burst due to too much osmotic pressure. Think of a Sump Pump.
The black swimming lines are bacteria. Also, the other reply is mostly correct except that Paramecium is a protist, not a bacterium. That's why it's so much bigger than those little bacteria sticks.
Good
Is that like a heart on unicellular scale ? It seems like it does same role to me.

سبحان الله 💕
What is the use of contractile vacuole in amoeba.
They absorb the food too
It's like their bladder.
how cute

No brain, no mind, no awaress.
Yet they seem to react on being "touched" like when they collide with eachother.🤔
Do they have nerves?
Quran H41-V53 ""We will show them Our signs in the horizons and within themselves until it becomes clear to them that it is the truth. But is it not sufficient concerning your Lord that He is, over all things, a Witness?""
