Binary fission and multiple fission both are types of asexual reproduction.
Binary fission :-
In this mode of asexual reproduction, the parent body divides into two nearly equal and identical individuals.
It occurs during favorable conditions.
Example – Amoeba, Paramecium etc.
Multiple fission :-
In this mode of asexual reproduction, the parent divides inside a protective covering called cyst, into many daughter cells.
On the onset of favorable conditions, the cyst wall ruptures and daughter cells are released.
It occurs during unfavorable conditions.
Example :- Amoeba, Plasmodium etc.
Final answer :-
Hence, this is the definition of binary fission and multiple fission.
