Detailed explanation-1: -Unicellular organisms can be prokaryotes or eukaryotes. Prokaryotes do not have cell nuclei: their structures are simple. Bacteria and archaea are all unicellular prokaryotes. Eukaryotes do have cell nuclei and their structures are more complex.

Detailed explanation-2: -While prokaryotes are always unicellular organisms, eukaryotes can be either unicellular or multicellular.

Detailed explanation-3: -Actinomyces and cyanobacteria are well-studied prokaryotes that exhibit multicellular forms (Claessen et al., 2014). Their reproducible multicellular structures achieve a high fitness for the whole population even though they are not beneficial for partial individuals.

Detailed explanation-4: -It’s also difficult to integrate them into a prokaryotic cell due to their small size and lack of membrane bound nucleus and other organelles.As a result, a multicellular prokaryote is not possible.

Detailed explanation-5: -Eukaryotes may be either single-celled or multicellular. Eukaryotes are differentiated from another class of organisms called prokaryotes by way of the presence of internal membranes that separate parts of the eukaryotic cell from the rest of the cytoplasm.
