How is the prokaryotic bacterium in the diagram different from eukaryotic cell?

Prokaryotic bacteria differ from eukaryotic cells primarily in their structure and complexity. Bacteria lack a nucleus; their genetic material is contained in a nucleoid region, while eukaryotic cells have a defined nucleus that houses their DNA. Additionally, prokaryotic cells are generally smaller and simpler, lacking membrane-bound organelles found in eukaryotes. Eukaryotic cells also possess a more complex cytoskeleton and can be unicellular or multicellular, unlike most prokaryotes, which are unicellular.
