Which statement describes single-celled microorganisms that lack nuclei and organized cell structures?

Explanation:
Single-celled organisms that lack nuclei and organized membrane-bound cell structures are prokaryotes. Bacteria are classic examples of prokaryotes, having DNA in a nucleoid region and no true nucleus or Membrane-bound organelles. Red blood cells and white blood cells are human cells with nuclei and organized organelles, so they don’t fit this description. The description therefore matches bacteria.
