/ˈzəʊəspɔː/, U.S.

/ˈzoʊəˌspɔr/,

/ˈzu(ə)ˌspɔr/

Forms: see zoo- comb. form and spore n.

Origin: Formed within English, by compounding; modelled on a French lexical item. Etymons: zoo- comb. form, spore n.

Etymology: < zoo- comb. form + spore n., after French zoospore (J. Decaisne 1842, in Ann. des sci. nat.: Botanique 17 307).

Biology.

A motile flagellate spore, as produced by certain algae, fungi, and protozoans. Cf. zoosperm n. 2.macrozoospore, megazoospore, microzoospore, zygozoospore: see the first element.Numerous zoosporic organisms are pathogens causing disease in economically significant plant and animal species.
