fission

 [fish´un]
1. the act of splitting.
2. asexual reproduction in which the cell divides into two (binary fission) or more (multiple fission) daughter parts, each of which becomes an individual organism.
3. nuclear fission; the splitting of the atomic nucleus, with release of energy.
binary fission the halving of the nucleus and then of the cytoplasm of the cell, as occurs in protozoa.

binary fission

an asexual method of cell reproduction (see ASEXUAL REPRODUCTION carried out by PROKARYOTES and some primitive EUKARYOTES, in which the chromosomal material is replicated and then the cytoplasm splits by CYTOKINESIS. Such processes differ from MITOSIS and MEIOSIS in that the chromosomal separation does not involve cellular MICROTUBULES forming a spindle.
