binary fission
binary fissionn. A form of asexual reproduction in bacteria and other prokaryotes that involves the splitting of a parent cell into two independent cells.binary fission n (Biology) asexual reproduction in unicellular organisms by division into two daughter cells bi′nary fis′sion n. fission into two organisms roughly equal in size. binary fission See fission.Translationsbinary fission
binary fission[′bīn·ə·rē ′fish·ən] (biology) A method of asexual reproduction accomplished by the splitting of a parent cell into two equal, or nearly equal, parts, each of which grows to parental size and form. binary fission
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·sionsimple fission in which the two new cells are approximately equal in size.binary fissionn. A method of asexual reproduction that involves the splitting of a parent cell into two approximately equal parts.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.ThesaurusSeefission |
