You identify a novel living organism that needs to be classified into one of the three domains of life. The organism has a cell wall containing pseudopeptidoglycan (pseudomurein), a plasma membrane, and a nucleoid region. Based on this information, which of the three domains would be the correct classification?ANSWERProkaryotesBacteria and ArchaeaBacteria onlyArchaea only
Question
You identify a novel living organism that needs to be classified into one of the three domains of life. The organism has a cell wall containing pseudopeptidoglycan (pseudomurein), a plasma membrane, and a nucleoid region. Based on this information, which of the three domains would be the correct classification?ANSWERProkaryotesBacteria and ArchaeaBacteria onlyArchaea only
Solution
The correct classification for this novel organism would be "Archaea only". This is because the presence of a cell wall containing pseudopeptidoglycan (pseudomurein) is a characteristic feature of Archaea. Bacteria, on the other hand, have cell walls made of peptidoglycan. Both Archaea and Bacteria are prokaryotes, meaning they have a nucleoid region instead of a nucleus. However, the specific type of cell wall in this case points to the organism being an Archaea.
