You are referring to a prokaryotic cell such as the bacteria, E.coli.
Prokaryotes DO NOT have a nucleus, they have genetic material (DNA) that free floats in the cytoplasm. The definition of a nucleus is that the genetic material is surrounded by an internal membrane.
Prokaryotes all are unicellular but can grow in close proximity to each other called colonies.
A prokaryote is a single-celled organism that doesn't have a membrane-bound nucleus. Escherichia coli, a kind of bacteria that can be dangerous to humans, is an example.
A prokaryotic cell is a single-celled organism that lacks a nucleus.
prokaryotic
These single celled organisms are called prokaryotes.
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.
An organism that's lacks a nuclear membrane. It doesn't have a true nucleus.
Prokaryotes and Viruses
A microbe is a prokaryotic type of cell, which means it lacks a nucleus and other organelles, and is a single-celled organism. Fungi are multi-cellular, and are eukaryotic, meaning they have a nucleus, and various organelles are contained within their cell membrane.
Bacteria is a single celled organism that lacks a nucleus, if that helps at all.
a Prokaryote
A prokaryote otherwise called a Moneran.
These single celled organisms are called prokaryotes.
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.

Prokaryote
The amoeba belongs to the kingdom Protista. It is a single-celled organism that lacks a defined nucleus and membrane-bound organelles.
Archaebcteria
An organism that's lacks a nuclear membrane. It doesn't have a true nucleus.
