Ch 19 and 20 Flashcards
binomial nomenclature
naming system - every species gets a unique 2 part name (genus species)
classification
arrangement of organisms into orderly groups based on similarities
systematics
science of naming and grouping organisms
Classification orders
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
early classification
based on physical features species with similar characteristics Animalia and plantae
bacteria
unicellular with no nucleus or membrane-bound organelles, has a cell wall - prokaryote
archaea
unicellular with no nucleus or membrane-bound organelles. different type of cell wall live in extreme conditions - prokaryote
eukarya
mix of unicellular and multicellular. they always have a nucleus - eukaryote
animalia
multicellular, heterotrophic, no cell wall, eukaryotic
Plantae
multi, autotroph, cell wall made of cellulose, eukaryotic
Protista
most are unicellular, heterotrophic or autotrophic, varying in cell wall, eukayotic
fungi
most are multicellular, heterotrophic, cell wall made with chitin, eukaryotic
dichotomous keys
identify species, two-part questions, physical characteristics
how do viruses reproduce
uses their genetic information to reproduce inside cells
archaea vs bacteria
cell walls, cell membranes, DNA sequences, harsh environments
eubacteria
unicellular, prokaryotic
archaebacteria
unicellular, prokaryotic
eukarya kingdoms
Protista, fungi, plantae, animalia
prokaryotes
unicellular, no nucleus, DNA is in the cytoplasm ,bacteria or archaea
pathogen
disease causing agent
vaccine
prep of weakened or killed pathogens or inactivated toxins
antibiotics
block growth and reproduction of bacteria
prokaryotes shape
bacilli, cocci, spirilla
protists
eukaryote, not a plant, animal, fungus
protists motion
cilia, flaggella
