The single-celled organism with a nucleus can be categorized into FUNGI OR PROTIST
- Living organisms has been classified into six kingdoms namely: Animalia, Plantae, Fungi, Protista, Monera and Archaebacteria.
- Among these kingdoms, kingdoms Animalia, Plantae, Fungi, and Protista are all EUKARYOTIC. This means that they possess a true nucleus in their cells.
