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.

bi·na·ry fis·sion

simple fission in which the two new cells are approximately equal in size.

binary fission

n.
A method of asexual reproduction that involves the splitting of a parent cell into two approximately equal parts.

binary fission

[bī′nərē]
Etymology: L, bini, twofold, fissionis, splitting
the division of a cell or nucleus into two equal parts. It is the common form of asexual reproduction among bacteria, protozoa, and other unicellular organisms. Also called simple fission. Compare multiple fission.

binary fission

Asexual reproduction in which a cell divides into 2 daughter cells after DNA replication and mitosis.

bi·na·ry fis·sion

(bī'nar-ē fish'ŭn)
Simple fission in which the two new cells are approximately equal in size.

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.
