English → English (gcide) Definition: Protozoa Protozoa \Pro`to*zo"a\, n. pl. [NL., fr. Gr. ? first + zo^,on an animal.] (Zo["o]l.) The lowest of the grand divisions of the animal kingdom. [1913 Webster] Note: The entire animal consists of a single cell which is variously modified; but in many species a number of these simple zooids are united together so as to form a compound body or organism, as in the Foraminifera and Vorticell[ae]. The reproduction takes place by fission, or by the breaking up of the contents of the body after encystment, each portion becoming a distinct animal, or in other ways, but never by true eggs. The principal divisions are Rhizopoda, Gregarin[ae], and Infusoria. See also Foraminifera, Heliozoa, Protoplasta, Radiolaria, Flagellata, Ciliata.
