The nature of the cell wall, the presence of an organized nucleus, and I don't know.
I will overlook your increasingly strident name-calling. Such boorish behavior!
I gained a bit of respect for you now. Do you know why. The simple words I don't know.
There are things we all don't know. Don't be so hard and think you are superior to others if they don't know even if they have different ideas than you.
Cell wall is one. And you described it correctly.
The two main others would be mitochondria and the main one would be the ribosomes. (Ribosomal and the presence of mitochondrian in eukaryotes are related -- extra credit for whomever can say why).
There are others -- prokaryotes do not have introns.
Take care, vade.
