Ribosomes,cytoplasm ,cell wall and circular DNA could be used to justify that the cell is a prokaryote.
Explanation:
Ribosome Ribosome is present in both prokaryotic cell and eukaryotic cell.The prokaryotic cell 70S ribosome which contain 2 subunits the larger subunit is 50S and the smaller subunit is 30s
Cell wall Prokaryotes such as bacterial cell contain cell wall.Cell wall of bacteria contain various carbohydrates which are crosslinked with peptides resulting in the formation of peptidoglycan.
Cytoplasm The cytoplasm of prokaryotic cell such as bacteria contain ribosomes,chromosome and extracellular genetic material called plasmid.
Circular DNA Almost all prokayotic chromosome contain circular DNA molecule that does not contain any free ends.
Organisms were classified into a large group called DOMAIN. The domain consists of two main types of organisms: PROKARYOTES AND EUKARYOTES. The basis of this classification is the possession or not of a well defined nucleus.
Prokaryotic organisms contains a single, circular naked genetic material found in a region of the cytoplasm called NUCLEOID. They do not have a nucleus that houses their genetic material (DNA). However, on the other hand, EUKARYOTES possess a linear chromosome that is enclosed by a membrane bound nucleus.
Therefore, although prokaryotes and eukaryotes have many structural distinctions, one can justify an organism being classified as a prokaryote by the possession of a circular genetic material (DNA).
