Multiple fission is also an asexual method of reproduction in organisms.In multiple fission,the parent organism splits to form many new organisms at the same time.   This happens as follows:-
a cyst or a protective wall is formed around the cell of a single-celled organism. inside the cyst,the nucleus of cell splits several times to form smaller nuclei called daughter nuclei around them.In this way,many new daughter cells are formed from a single parent within the cyst & when the favourable conditions arrive,the cyst breaks open and the many daughter cells present in it are released,each forming a new organism.In this way,a single celled parent undergoes multiple fission to reproduce many daughter cells at the same time.Plasmodium is a protozoan(a microscopic,singled celled animal) which reproduces by asexual method of multiple fission.
