Similarities between Prokaryotic
Prokaryote
A prokaryote is a unicellular organism that lacks a membrane-bound nucleus, mitochondria, or any other membrane-bound organelle. The word prokaryote comes from the Greek πρό "before" and κάρυον "nut or kernel". Prokaryotes are divided into two domains, Archaea and Bacteria. Species wit…
