Paramecium is a ciliate, a group of single-celled animal-like creatures (protists) that have a rather unusual way of reproducing. Most protists (and cells in animals and plants) have a single nucleus which, once all the chromosomes have been duplicated, splits in half, along with the rest of the cell. Ciliates, however, are different: they have at least two nuclei: a large macronucleus and a tiny micronucleus. So, both nuclei must divide.
