Beside of many similarities between prokaryotic and eukaryotic cells, there are some differences between these two as well. These differences are discussed in following paragraph. Prokaryotic cells have a well defined nucleus with double membrane while prokaryotic cells don't. DNA of eukaryotic cells is linear while that of prokaryotic cells is circular. DNA of eukaryotic cells is present in chromosomes and is complexed with histones which are protein in nature while DNA of prokaryotic cells is without histones and not arranged in chromosomes. Prokaryotic cells contain single while eukaryotic cells contain many chromosomes. Ribosomes of eukaryotic cells are large and complex than that of prokaryotic cells. Cytoplasm of eukaryotic cells has membrane bonded organelles while that of prokaryotic cells without any membrane.
E. Colli Bacterium and Salmonella Bacterium are examples of prokaryotic cells true or false
