In fact, all prokaryotes lack any membrane bound organelle. And this includes organelles such as the mitochondria, the Golgi apparatus, the endoplasmic reticulum, and so forth. All these membrane banned organelles that are found in eukaryotes are not found in prokaryotes. So what exactly is the structure of a prokaryotic organism? So, in this lecture, we're going to briefly discuss the general structure of the prokaryotic organism. We're going to examine some of the shapes of our prokaryotes, and then we'll briefly discuss the major differences between prokaryotes and eukaryotes.
