We can have our basili, which is basically this rod like shape, which is this organism we drew in this diagram here. And we can also have a spiral like shape, a helical shape, as shown, and this is known as the SPIROLA. So the spirilla, our bacilli and our Coxy. These are the different types of shapes that our prokaryotic organisms can take. Now, what exactly are the sum of the differences that we should know between prokaryotic organisms and our eukaryotic organisms? So, as we discussed earlier, prokaryotes have two domains.
