• Monerans possess naked DNA and RNA not associated with proteins
• The cell wall is made up of peptidoglycan  
• Membrane-bound cell organelles like mitochondria, Golgi complex, endoplasmic reticulum etc are absent in monerans
• Ribosome of 70 S type is present in these organisms.
• Reproduction in these organisms mainly occurs by asexual means i.e. binary fission, endospore production etc.
