KINGDOM S ARCHAEBACTERIA AND EUBACTERIA

KINGDOM MONERA Oldest and most numerous

organism on Earth Found in every environment

on Earth Unicellular Prokaryotic – has no

nucleus or membrane bound organelles

MONERANS – TWO KINGDOMS Kingdom Monera is now divided into two different

Kingdoms due to differences in RNA Kingdom Archebacteria Kingdom Eubacteria

KINGDOM EUBACTERIA Represents most of the bacteria, thus in general are

called “bacteria” Names based on shape

SHAPES AND NAMES: Bacilli – Rod Shaped Cocci – Sphere Shaped Spirilla – Spiral Shaped

CHAINS AND CLUSTERS OF COCCI: Chains of Cocci – Streptococci Grape like clusters of Cocci – Staphylococci

KINGDOM ARCHAEBACTERIA: RNA structure and synthesis very different to bacteria,

closer to eukaryotic (nuclei based organisms) Typically found in the most extreme of environments

(high heat, low nutrients, no light)

BACTERIA STRUCTURE: All are prokaryotic All have cell walls Can move by cilia, flagellum,

or lots of flagellum

BACTERIA & HUMANS Bacteria can be harmful to the body because it either

produces toxins or destroys body tissues Antibiotics kill some bacteria, but the ones that survive

could potential build a population of antibiotic resistant bacteria
