What are Single celled organisms that have no organized nuclei called?
Single-celled organisms that do not have organized nuclei are called prokaryotes. These organisms are simple in structure and lack a membrane-bound nucleus. Examples of prokaryotes include bacteria and archaea.
What characteristics do Monera and Prokaryocytes share?
Prokaryotes are part of the Monera kingdom. They have the same characteristics.
What is a characteristics prokaryotic?
Prokaryotes do not have a membrane-bound nucleus or other membrane-bound organelles.
Does a eurokaryote have a nucleus?
Yes, eukaryotes have a nucleus. On the other hand, prokaryotes do not have a nucleus. Eukaryotes also have numerous other characteristics not found in prokaryotes, the nucleus is simply the most well known.
Do Prokaryotes have Prokaryotes?
yes prokaryotes have prokaryotes
The other domain of unicellular prokaryotes?
The other domain of unicellular prokaryotes is Archaea. Archaea are a distinct group of single-celled organisms that have characteristics of both bacteria and eukaryotes. They are known for their ability to thrive in extreme environments, such as hot springs and deep-sea vents.
What is another word for prokaryotes?
Bacteria is also known as prokaryotes Bacteria is also known as prokaryotes
