Answer:
Prokaryotes lack a true nucleus with well defined nuclear membrane and other membrane-bound organelles. Mitochondria are the double membrane bound organelle and hence is absent in prokaryotes. Mesosome is an extension of the cell membrane presence in the cytoplasm as infolding and serves to increases surface area and as a site for cellular respiration in prokaryotes. Histones are positively charged proteins that serve in the packaging of negatively charged eukaryotic DNA but are absent in prokaryotes.
