How quickly can mitosis occur in paramecium?

2 millimeters per second,

Explanation:

During binary fission, one paramecium cell divides into two genetically identical offspring, or daughter cells. According to Forney, the micronucleus undergoes mitosis, but the macronucleus divides another way, called an amitotic, or non-mitotic, mechanism.Cilia are essential for movement of paramecia. As these structures whip back and forth in an aquatic environment, they propel the organism through its surroundings. Paramecia can move forward at rates up to 2 millimeters per second,
