Answer:
Prokaryote Organisms
Explanation:
Prokaryote Organisms are usually smaller and simpler than eukaryotic cells. They do not have a nucleus or other membrane-bound organelles. In prokaryotic cells, the DNA, or genetic material, forms a single large circle that coils up on itself.
There are two types of organisms based on the presence of a nucleus, namely, prokaryotic organisms and eukaryotic organisms. Prokaryotes do not have nucleus.
Prokaryotes are the organisms lacking true nucleus and other membrane bound organelles and are unicellular.
These organisms includes bacteria, archaebacteria, etc.
Prokaryotes have genetic material in the form of a single chromosome, of circular DNA.
The DNA in prokaryotes is present in a central area of the cell called the nucleoid, where nuclear membrane is absent.
Many prokaryotes carry small, circular DNA molecules which called plasmids.
Thus, the organism that do not possesses a nucleus is prokaryote.
