An example of a prokaryotic cell is a bacterial cell, such as Escherichia coli (E. coli).

What “prokaryotic” means

  • Prokaryotic cells are cells that do not have a membrane‑bound nucleus or other membrane‑bound organelles.
  • Their DNA sits in a region called the nucleoid instead of in a true nucleus.

Common examples

  • Bacteria, including E. coli , Streptococcus , and Staphylococcus , are classic examples of prokaryotic cells.
  • Archaea (a group of single‑celled microbes often living in extreme environments) are also made of prokaryotic cells.

Quick comparison to your cells

  • Prokaryotic cells are usually single‑celled and structurally simpler than human (eukaryotic) cells.
  • Human skin cells or nerve cells are not prokaryotic; they are eukaryotic because they have a nucleus.

In short: when asked “what is an example of a prokaryotic cell?”, answering “a bacterial cell such as E. coli ” is correct and precise.
