Which of the following is a characteristic of prokaryotic cells?

Prokaryotic cells are defined by their simpler structure compared to eukaryotic cells. One of their most distinguishing characteristics is that they typically have a single cell structure, meaning they are unicellular organisms. This characteristic encompasses bacteria and archaea, the two domains of prokaryotes. Since prokaryotic cells lack membrane-bound organelles, a nucleus, and they are primarily unicellular, this reinforces that they operate on a much simpler level compared to multicellular organisms and cells with complex organelles. Understanding this fundamental aspect is crucial for recognizing how prokaryotic cells function and how they differ from eukaryotic cells in various biological processes.
