archaeabacteria and eubacteria both are single cell organisms without nucleus
A eukaryote is a single celled organism have a nucleus. Different types of eukaryotic cells are found in plants and animals. A double membrane surrounds the nucleus in these cells.
These single celled organisms are called prokaryotes.
Monerans are prokaryotes.
Amoeba is a primitive single celled organism.
Bacteria lacks a nucleus but have a fully developed DNA, thus they can be considered full cells. Virus also lack a nucleus, but they have not a fully developed DNA. Even virus having RNA only exist. For this reason virus are somehow in between cells and simple multiple molecular systems.
==The Final Answer. . .== Eubacteria is a single celled organism, just like its [so called] twin, Archaebacteria.
These single celled organisms are called prokaryotes.
A prokaryote otherwise called a Moneran.
A single-celled organism without an organized nucleus is a prokaryote.
Bacteria is a single celled organism that lacks a nucleus, if that helps at all.

a single celled organism is called unicellular an example is yeast

A single-celled organism is said to be unicellular.
