Membranes. Most prokaryotes are bacteria, while humans, animals, plants and fungi are eukaryotes.The prokaryotic cell has only one membrane, the plasma membrane, which surrounds its cellular contents.The eukaryotic cell also has a plasma membrane, but, in addition, it is filled with many membrane-enclosed compartments.itochondria and Chloroplasts.
