Prokaryotic and eukaryotic cells are the two categories of living cells based on complexity. These two types of cells share many similarities and differences; some are more obvious than others. A very obvious difference between these two cells is that prokaryotic cells are much smaller than eukaryotic cell and eukaryotic cells are much more complex than prokaryotic cells. If you were to look at a prokaryotic cell you would see few organelles compared to eukaryotic cells which have many organelles to complete specialized activities for the cell. Because of their differences in complexity prokaryotic cells are in bacteria and single cell organisms while eukaryotic cell are in plants and are mostly found in animals. The other difference that you can see from looking at a diagram of these two cells is that a prokaryotic cell has no nuclear membrane while a eukaryotic cells nucleus does have a membrane. There are also many similarities shared by these two types of cells. Though prokaryotic and eukaryotic cells have varying amounts of organelles they both require a lot of the same function in order for the cell to survive. Both prokaryotic and eukaryotic cells have the same kind of DNA and the same genetic code. Both cells also need oxygen most of the time to survive. Some parts that both prokaryotic and eukaryotic cells contain are cytoplasm and ribosomes. Though these cells have different characteristics they are both very good for the functions that they are meant to serve.
