A prokaryotic cell is a single-celled organism with no membrane-bound nucleus, mitochondria, or other membrane-bound organelles.
All internal water-soluble components (proteins, DNA, and metabolites) are found in the cytoplasm, which is surrounded by the cell membrane, rather than in discrete cellular compartments in prokaryotic cells.
Cyanobacteria and other prokaryotes can create huge colonies.
Myxobacteria, for example, exhibit multicellular stages in their life cycles.
