<span>For example, a prokaryotic cell is an uncivilized society while the eukaryotic cell is a more systematized society, with coordination and cooperation and a leader.
Eukaryotic cells has a nucleus while prokaryotic cells do not. Eukaryotic cells have more than one chromosomes and is usually multicellular while the prokaryotic cells has only one chromosome and it's not even a genuine one, only plasmids and has unicellular however some cyanobacteria maybe multicellular. Eukaryotic cells have genuine membrane-bound nucleus, lysosomes and peroxisomes while prokaryotic cells display just the opposite of eukaryotic cells. Eukaryotic cells recombines its genes by meiosis and by the fusion of gametes while the prokaryotes does by partial and undirectional transfer of DNA.</span>
