The protozoa ko protozoa su ne microscopic, unicellular kwayoyin da m abun da ke ciki zuwa juna. Suna zaune a wurare masu zafi ko wuraren ruwa.

Daga mahangar asalin kalmar kalmar protozoon Ya ƙunshi kalmomi biyu: "proto" wanda ke nufin na farko da "zoo" wanda ke nufin dabba.

Ana iya ganin irin wannan ƙananan ƙwayoyin cuta a ƙarƙashin na'urar microscope. Suna iya girma zuwa milimita. A halin yanzu an gano su 50,000 nau'in protozoa. Suna da aiki sarrafa kwayoyin cutar kwayan cuta.

Ana gabatar da hanyar numfashin su ta hanyar membran tantanin halitta kuma suna amfani da barbashin ruwa don yin hakan (tunda suna rayuwa a cikin mahalli inda ɗimbin zafi yake akai). Suna ciyar da algae, fungi ko kwayoyin cuta.

Yawanci irin wannan sel yana faruwa a sifar parasites a cikin dabbobi da tsire -tsire.
