Paramecium cells are unicellular organisms. They are part of the eukaryotic family. Thus they have membrane-bound organelles.

They can also be categorised as Ciliates, since they are surrounded by numerous cilia; these assist the cytostome for the nutrition process of paramecium and also the movement of the cell. They also have anal pores for excretion processes and contractile vacuoles whose function prevents bursting of the cell, which would otherwise be caused by the osmotic uptake of water, by a process known as osmoregulation [1]. The Paramecium cell reproduces by a process calledconjugation.[2]

Paramecium cells are very large. The length of a typical paramecium varies from 100 μm to 300 μm [3]. They can be found in freshwater areas, like ponds and lakes.
