Yes. Both Prokaryotic Cells and Eukaryotic Cells have an outer cell membrane. But, prokaryotic cells do not have membranes around their organelles
Prokaryotic cell-to-cell signaling systems evolved through mechanisms like natural selection, quorum sensing, horizontal gene transfer, evolution of signal molecules, and symbiotic relationships. These processes enabled bacteria to communicate, coordinate behaviors, and enhance survival. The interactions among these mechanisms contribute to the persistence and complexity of signaling systems in prokaryotes.
