Living things have evolved into three large clusters of closely related organisms, called domains: Archaea, Bacteria, and Eukaryota. Archaea and Bacteria are small, relatively simple cells surrounded by a membrane and a cell wall, with a circular strand of DNA containing their genes.They are called prokaryotes.iving things have evolved into three large clusters of closely related organisms, called domains: Archaea, Bacteria, and Eukaryota.

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.
