No nucleus or complex organelle- unicellular

Explanation:
Having no nucleus or membrane-bound organelles and typically existing as single cells defines prokaryotes. In these cells, DNA is located in a nucleoid region rather than a true nucleus, and there are no complex organelles like mitochondria or endoplasmic reticulum. This simple cellular layout contrasts with eukaryotes, which have a nucleus and many organelles and are usually multicellular. Viruses aren’t cells at all and don’t carry out cellular life independently. Fungi are eukaryotes with a nucleus and organelles, and even their unicellular forms (like yeasts) have a true nucleus. So the description best fits a prokaryote.
