Kingdoms & Domains Chapter 18-3
2
As we discovered more about the natural world…
not all organisms fit into Linnaeus’s 2 kingdoms (_____ or _____) plant animal bacteria fungi Ex: _________ _____ Images from:
3
_______________________ FIVE ORIGINAL KINGDOMS
(BACTERIA)
4
6 KINGDOMS used today As we learned more about bacteria,
the __________ kingdom was split into TWO distinct kingdoms ___________ & ______________ MONERA Eubacteria Archaebacteria 6 KINGDOMS used today Eubacteria Archaebacteria Protista Plantae Fungi Animalia
5
THREE-DOMAIN system Molecular analyses have given
rise to a ___________ _______ now recognized = _______ new taxonomic category DOMAIN
6
Domains are larger than Kingdoms and are based on the kind of
Bacteria Archaea Eukarya Eubacteria Archaebacteria Protista Plantae Fungi Animalia Domains are larger than Kingdoms and are based on the kind of ____________ an organism has. Ribosomal RNA

= ____________ (Includes bacteria)
REMEMBER Cell without a nucleus = ____________ (Includes bacteria) Cell with a nucleus and organelles surrounded by membranes = _________________ (includes plants and animals) Organism that can make its own food using photosynthesis or chemosynthesis = ______________ Organism that gets food energy from consuming other organisms = _____________ PROKARYOTE EUKARYOTE AUTOTROPH HETEROTROPH
9
= _____________________
REMEMBER A ONE-CELLED organism = _____________________ Organism made of many cells = ______________ Polysaccharide made by joining glucose molecules together which makes plants sturdy = _________________ UNICELLULAR MULTICELLULAR CELLULOSE
10
DOMAIN: BACTERIA KINGDOM: EUBACTERIA
_______________________ ______________________ Have cell walls with ________________ Can be ____________ or ______________ EXAMPLES: _____________________ PROKARYOTES UNICELLULAR PEPTIDOGLYCAN AUTOTROPHS HETEROTROPHS E. coli, Streptococcus
11
Polymer made of sugars and amino acids
found outside the cell membrane in the cell wall in some bacteria = ______________ PEPTIDOGLYCAN
12
DOMAIN: ARCHAEA KINGDOM: ARCHAEBACTERIA
PROKARYOTES _________________ Have cell walls _________ peptidoglycan Can be ___________ or ______________ EXAMPLES: _____________________ LIVE IN EXTREME ENVIRONMENTS like volcanic hot springs, brine pools, low oxygen UNICELLULAR WITHOUT AUTOTROPHS HETEROTROPHS Halophiles; thermophiles;
13
Organisms that can live in HIGH temperature environments
Organisms that can live in HIGH temperature environments = ________________ Organisms that can live in high salt environments = ______________ THERMOPHILES HALOPHILES
14
DOMAIN: EUKARYA KINGDOM: PLANTAE
_______________________ ______________________ Have cell walls with ________________ and _____________ _________________ EXAMPLES: _____________________ EUKARYOTES MULTICELLULAR CELLULOSE CHLOROPLASTS AUTOTROPHS Mosses, ferns, trees, flowering plants
15
DOMAIN: EUKARYA KINGDOM: ANIMALIA
DOMAIN: EUKARYA KINGDOM: ANIMALIA _______________________ _____________________ ________________ or _______________ __________________ EXAMPLES: _____________________ EUKARYOTES MULTICELLULAR NO CELL WALLS CHLOROPLASTS HETEROTROPHS Worms, insects, fish, birds, mammals, humans
16
DOMAIN: EUKARYA KINGDOM: FUNGI
_______________________ ______________________ Have cell walls with ________________ _______________ __________________________________ EXAMPLES: _____________________ EUKARYOTES Most MULTICELLULAR; few UNICELLULAR CHITIN HETEROTROPHS- absorb nutrients from decaying organic matter Mushrooms, yeast
17
DOMAIN: EUKARYA KINGDOM: PROTISTA
_______________________ ______________________ Some have cell walls with ________________ ____________________ Can be _____________ or _____________ EXAMPLES: _____________________ EUKARYOTES Most UNICELLULAR; some colonial/multi CELLULOSE Some have chloroplasts AUTOTROPHS HETEROTROPHS Amoeba; Paramecium; Giant kelp; slime mold
