Eukaryotic cells have membrane-bound organelles and a nucleus, while prokaryotic cells lack internal compartmentation. The new organism described would be classified as a prokaryote due to the absence of mitochondria and endoplasmic reticulum.
Eukaryotic cells have membrane-bound organelles and a membrane-bound nucleus, while prokaryotic cells lack internal compartmentation like mitochondria and nuclei. Given the characteristics of the new organism – containing DNA and ribosomes but lacking mitochondria and endoplasmic reticulum – it would be classified as a prokaryote based on the absence of these membrane-bound organelles.
