Accrementition :: Accrementition (n.) The process of generation by development of blastema, or fission of cells, in which the new formation is in all respect like the individual from which it proceeds..

Schizomycetes :: Schizomycetes (n. pl.) An order of Schizophyta, including the so-called fission fungi, or bacteria. See Schizophyta, in the Supplement..

Strobile :: Strobilation (n.) The act or phenomenon of spontaneously dividing transversely, as do certain species of annelids and helminths; transverse fission. See Illust. under Syllidian..

Fissigemmation :: Fissigemmation (n.) A process of reproduction intermediate between fission and gemmation.

Holoblastic :: Holoblastic (a.) Undergoing complete segmentation; composed entirely of germinal matter, the whole of the yolk undergoing fission; -- opposed to meroblastic..

Pseudofilaria :: Pseudofilaria (n.) One of the two elongated vibratile young formed by fission of the embryo during the development of certain Gregarinae.

Fission :: Fission (n.) A method of asexual reproduction among the lowest (unicellular) organisms by means of a process of self-division, consisting of gradual division or cleavage of the into two parts, each of which then becomes a separate and independent organisms; as when a cell in an animal or plant, or its germ, undergoes a spontaneous division, and the parts again subdivide. See Segmentation, and Cell division, under Division..

Deuterozooid :: Deuterozooid (n.) One of the secondary, and usually sexual, zooids produced by budding or fission from the primary zooids, in animals having alternate generations. In the tapeworms, the joints are deuterozooids..

Fissipara :: Fissipara (n. pl.) Animals which reproduce by fission.

Encystment :: Encystment (n.) A process which, among some of the lower forms of life, precedes reproduction by budding, fission, spore formation, etc..

Scissiparity :: Scissiparity (n.) Reproduction by fission.

Meroblastic :: Meroblastic (a.) Consisting only in part of germinal matter; characterized by partial segmentation only; as, meroblastic ova, in which a portion of the yolk only undergoes fission; meroblastic segmentation; -- opposed to holoblastic..

Protophyte :: Protophyte (n.) Any unicellular plant, or plant forming only a plasmodium, having reproduction only by fission, gemmation, or cell division..

Sporid :: Spore (n.) One of the parts formed by fission in certain Protozoa. See Spore formation, belw..

Schizogenesis :: Schizogenesis (n.) Reproduction by fission.

Schizo- :: Schizo- () A combining form denoting division or cleavage; as, schizogenesis, reproduction by fission or cell division..

Individual :: Individual (n.) The product of a single egg, whether it remains a single animal or becomes compound by budding or fission..

Leptothrix :: Leptothrix (n.) Having the form of a little chain; -- applied to bacteria when, as in multiplication by fission, they form a chain of filiform individuals..

Fission :: Fission (n.) A cleaving, splitting, or breaking up into parts..

Bacterium :: Bacterium (n.) A microscopic vegetable organism, belonging to the class Algae, usually in the form of a jointed rodlike filament, and found in putrefying organic infusions. Bacteria are destitute of chlorophyll, and are the smallest of microscopic organisms. They are very widely diffused in nature, and multiply with marvelous rapidity, both by fission and by spores. Certain species are active agents in fermentation, while others appear to be the cause of certain infectious diseases. See Bacillus
