Is Paramecium unicellular or multicellular?

Paramecium is a unicellular microorganism

Paramecium (pair-ah-me-see-um; plural, Paramecia) is a unicellular (single-celled) living organism with a shape resembling a slipper. Paramecium is naturally found in aquatic habitats. You need a microscope to see the paramecia because they are only 50 to 300 µm (micrometers) in length.

Although paramecium is small and has only one cell, it can do everything that a living creature can do: Paramecium can swim, digest food, and reproduce. Paramecium’s cell contains several complex organelles performing specific functions to make its survival possible.

Each structure/organelle and its function will be explained in this article.
