Protozoa are single-celled eukaryotes that contain a nucleus and organelles within their cell membrane. Many protozoa engage in symbiotic relationships, which involves an intimate association between two organisms where one organism is parasitic to the other. Symbiosis can occur when a protozoan lives inside or on the surface of another organism and derives nutrients or shelter from its host.
