Welcome to this unique "Prokaryotic Cells Quiz" that is going to test your knowledge about prokaryotic cells. Prokaryotic cells are unicellular organisms that lack a membrane-bound nucleus, mitochondria, or any other membrane-bound organelle. They are divided into two domains; Archaea and Bacteria. What do you know about this particular organism? Let's find out with this amazing quiz right here right now. We wish you all the best to you. Have fun!
