The presence of a nucleus with linear chromosomes and a membrane indicates that the organism is a eukaryote. Presence of mitochondria and 80s ribosomes supports this as well. The presence of cilia further suggests that this is a unicellular protozoan rather than a multicellular organism like algae or fungus. There is no mention of a cell wall, which rules out bacteria and archaea as they have cell walls.
