Summary Introduction
Concept Introduction: Ciliates are diverse group of heterotrophs that lives anywhere water. Macronucleus and micronucleus are the two types of nucleus that are present in cilia. The macronucleus is a large polyploidy nucleus that controls the daily function. In the asexual reproduction of ciliates, the macronucleus undergoes mitosis division. The micronucleus is the smaller nucleus that functions in the sexual reproduction.
