Study Notes

Hierarchical Classification

Closely related species are grouped together in a hierarchical system
The system progresses from the most specific (species) to the broadest (kingdom)
The order of classification is: Species, Genus, Family, Order, Class, Phylum, Kingdom

Five Kingdoms

The modern classification system uses five kingdoms.
Kingdom Prokaryotae: Organisms in this kingdom have cells that lack a true membrane-bound nucleus. Their DNA is free within the cells.
Other Four Kingdoms: The remaining kingdoms consist of eukaryotes, organisms whose cells have true nuclei surrounded by membranes.

Viruses

Viruses are not classified into any of the five kingdoms.
They are not cellular organisms, but rather particles composed of DNA or RNA encased in a protein coat.
Viruses can only reproduce inside other living cells.
