So there are three major shapes that prokaryotic organisms can basically have. So they can either be round, which is basically our Coxy. So coccy means we have a round shape. 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.
