taxanomy
classification that uses two names
binomial nomenclature
1st being genus or generic name (being capitalied)
and 2nd being the species name or epiphet (in small letters)
Hierarchy of Biological Classification
Domain- kingdom-phyum-class-order-family-genus-species
- prehistoric bacteria
- 1st inhabbitant of Earth
ex. ) methanogens: Bacteria that can live in high concentrations of methane
Archaebacteria
- 1st true bacteria
- descendants of Archaebacteria
Eubacteria
-organisms with membrane and bound organelles
Eukarya
- prokaryotic cell organization
- arkaebacteria and eubacteria
Monera
- eukaryotic organism
- different forms:
a. algae- plant like
b. protozoans- animal-like
c. slime and water molds- fungal-like
protista
- eukaryotic organism
- immobile
- chitin cell walls (chitin fibrous substance)
fungi
