Prokaryotic cells are characterized primarily by their lack of a defined nucleus. Instead of being enclosed within a nuclear membrane, their genetic material, which is typically a single circular chromosome, is found in a region known as the nucleoid. This fundamental trait distinguishes prokaryotes from eukaryotic cells, which do have membrane-bound organelles, including a defined nucleus where their genetic material is housed.

The absence of a nucleus in prokaryotic cells means that their cellular processes, such as transcription and translation, occur simultaneously in the cytoplasm. This arrangement allows for more rapid growth and division compared to eukaryotic cells, which must process and transport their genetic material through nuclear membranes.

While discussing prokaryotic cells, it is essential to note that cells without a defined nucleus do not typically undergo sexual reproduction in the way that eukaryotic cells do. Instead, they primarily reproduce asexually through binary fission, where one cell divides into two. Furthermore, prokaryotic cells are generally unicellular and possess a simpler structure compared to eukaryotic cells, which can be multicellular and contain multiple chromosomes organized within multiple linear strands. Thus, the defining characteristic of prokaryotes is their lack of
