The term fission is a very common term used in both biology and physics. In both the subjects, fission has the same meaning; it means the division of one into two or multiple. In physics, fission is the process in which the radioactive particle is divided into two parts with almost the same molecular masses. Along with these two sub-particles some neutrons or electrons are also produced which continues the fission process in a chain fashion. This fission is used in nuclear reactors which, in turn, provide us with electricity.
In biology, fission means the division of one cell into two cells and each cell regenerates on its own to create a complete cell. In biology, fission is of two types–binary fission, that is the offspring produced is two and multiple, in which the offspring produced are more than two. Fission is the main process due to which an organism gains growth and the cells are built to form a complete new creature.
