Unicellular organisms are organisms that have one cell. They are divided into two quite different types, from different classification kingdoms. 1  The prokaryotes, bacteria and archaea, have cells with no nucleus and a simple cell structure.2  Eukaryotes have a nucleus, and a more complex cell structure.nicellular organisms are organisms that have one cell.

A unicellular organism, also known as a single-celled organism, is an organism that consists of only one cell, unlike a multicellular organism that consists of more than one cell. Historically the simple single celled organisms have sometimes been referred to as Monads. The main groups of unicellular organisms are bacteria, archaea, protozoa, unicellular algae and unicellular fungi. Unicellular organisms fall into two general categories: prokaryotic organisms and eukaryotic organisms.
