Examples of Prokaryotes. Prokaryotes are all single-celled organisms, most of which you know of as bacteria. For example, the famous (or infamous) Escherichia coli bacterium is a prokaryote, as is the streptococcus bacterium responsible for strep throat. prokaryote is a cell without a nucleus and eukaryotes are cells that contain nuclei. There's one quick test to distinguish prokaryotes from eukaryotes: if you can see a single organism, it's a eukaryote.
Quick Answer. The five main groups of single-celled organisms are protozoa, archaea, bacteria, unicellular fungi and unicellular algae. While single-celled organisms can be either eukaryotic or prokaryotic, most are prokaryotes. The two domains into which prokaryotic cells are divided are archaea and bacteria.
