  Differences ans Similarities between Eukaryote  and  Prokaryotic Cells
                      
The differences between Eukaryote and Prokarytic cell are mostly due to the size complexity differences between the two cell types.However, the cell types still share same similarities. Scientist have suggested that the cells are similar because Eukaryotes may evolved from Prokaryotes.


Differences:

  1. Eukaryotic cells are much larger and more complex.
  2. Prokarytic cells do not have nucleus, while Eukarytic cells do. (Eukarytic cell are large enough that they need a nucleus to keep genetic activities close together and increase efficiency. But Prokarytic cells have a nucleoid were the genetic activity occurs.
  3. Eukayrtic DNA is linear and also organize into chromosomes and is complexes with specialized proteins called histones while Prokarytic DNA is circular  and it donot have histones proteins and also it's DNA does not form chromosomes.
  4. Eukaryotic Ribosomes are larger than Prokaryotic Ribosomes.
  5. Prokaryotes cytoplasm does not have organells.
Similaritis:
  1. Enclosed by  plasma membrane.
  2. Contain ribosomes.
  3. Have DNA.
  4. Filled with cytoplasm.
Examples:

  • E.coli, Lactobacillus and salmonella are Prokaryotes organism.
  • Amoeba, Paramecium and Euglena are Eukaryotes organism.
