Protozoa are a diverse group of organisms that are non-phototrophic, unicellular, eukaryotic microorganisms with no cell walls. In general, protozoa have different stages in their lifecycles. Trophozoites are the active, reproductive, and feeding stage.his group can often have complex lifecycles that require multiple host species. Many sporozoans cause disease. Of all the diseases caused by protozoa, the deadliest is malaria, caused by the sporozoan Plasmodium. When a female Anopheles mosquito bites a human, it is able to transmit Plasmodium into the bloodstream.
