I. Types of Organisms: A.  Prokaryotes: These organisms lack a nucleus and any well defined  organelles (“little organs”). This group includes all bacteria  ( Kingdom Monera ). This kingdom is divided into 2 lineages:  Archaebacteria (“Ancient Bacteria”) and Eubacteria (“True  Bacteria”). B.  Eukaryotes: Organisms that have a membrane bound nucleus as  well as defined organelles, e.g. Mitochondria, golgi bodies,  endoplasmic reticulum.  This group includes plants ( Kingdom  Plantae ); animals ( Kingdom Animalia ), as well as many single  Kingdom  Protista ); fungi ( Kingdom Fungi ).

 C.  Viruses: Not really considered a “living” organism. They are  obligatory intracellular parasites  that require a host cell to  survive and to reproduce because they totally lack any cellular  machinery of their own. They do not have nor belong to any  Kingdom.  Each type of virus can infect and parasitize only a  limited range of host cells, called  Host Range . There are  several bacteriophages (bacterial viruses) that can only  parasitize  E.coli .  Some viruses can have a broad host range;  Example: Rabies virus - infects a number of mammalian cells  such as human, dogs, racoons, skunks.
