If you were a single-celled organism, you’d probably want to be a Paramecium. It looks like a tiny slipper, covered in thousands of little hairs called cilia. These hairs beat in perfect rhythm, like a synchronized swimming team, to propel it through the water.
It even has a little “mouth” called an oral groove that sweeps food in. And here’s the sweetest part: it has two nuclei. One is for everyday living, and the other is a “backup copy” of its genetic information. It’s like having a computer that also prints out all your files, just in case.

Watch a Paramecium zoom around under a microscope, and you’ll see it bump into things, back up, and try again. It’s basically you trying to navigate a crowded grocery store aisle on a Saturday morning.
