What is the basic structure of a prokaryotic cell?

The basic structure of a prokaryotic cell is defined by its simplicity, particularly in the absence of membrane-bound organelles and a true nucleus. Prokaryotic cells, which include bacteria and archaea, have a cell membrane that encases the cytoplasm, but they do not have the distinct membrane-bound structures (like a nucleus or mitochondria) that are characteristic of eukaryotic cells. Instead, their genetic material is located in a region called the nucleoid, which is not enclosed within a membrane. This fundamental characteristic is what differentiates prokaryotic cells from eukaryotic cells, highlighting their simpler organization and cellular function.
