Prokaryote. Prokaryotes (or Monera) are some of the simplest living things. [1] They are unicellular organisms and they include two major divisions of simple living beings: bacteria, and Archaea. [2] They generally do not have a cell nucleus, nuclear membrane or cell organelles, however a small number of exceptions have been found.
Bacteria. Prokarioti (od starogrčkog pro = prije, ranije i karyon = orah, jezgra) su jednoćelijski organizmi kojima nedostaje ćelijsko jedro (nemaju oblikovanu jezgrinu ovojnicu) ni organele, osim ribosoma i nisu odvojeni u različite ćelijske odjeljke, već je sve zajedno ograđeno ćelijskim zidom.
