TAXONOMY AND NOMENCLATURE Flashcards
TAXONOMY
STUDY OF CLASSIFYING ORGANISMS INTO GROUPS BASED ON SIMILARITIES AND DIFFERENCES IN CHARACTERISTICS
BINOMIAL NOMENCLATURE
METHOD OF NAMING DEVELOPED BY CAROLUS LINNAEUS; WRITTEN BY USING THE GENUS NAME WITH A CAPITALIZED FIRST LETTER FOLLOWED BY THE SPECIES NAME USING SMALL LETTERS; ITALICIZED WHEN TYPE-WRITTEN (e.g. Oryza sativa)
ARCHAEA
SINGLE-CELLED PROKARYOTES; OBSERVED IN EXTREME ENVIRONMENTS
EUBACTERIA
COCCUS - SPHERICAL; BACILLUS - ROD SHAPED; SPIRILLUS - SPIRAL SHAPED
PROTISTA
DIVERSE SINGLE-CELL EUKARYOTES
FUNGI
MULTI CELLED HETEROTROPHS; OBTAINS NUTRIENTS BY DIGESTING FOOD OUT OF THEIR BODY BEFORE ABSORBING THEM
PARASITIC FUNGI
OBTAINS FOOD FROM LIVING ORGANISMS
SAPROPHYTIC FUNGI
OBTAINS FOOD FROM DECAYING MATTER
PLANTAE
MULTI-CELLED AUTOTROPHS; PRODUCE THEIR OWN FOOD USING LIGHT ENERGY
