DOMAINS AND KINGDOMS 17.3 pages

Today’s Essential Question: What are the similarities and differences among the 6 kingdoms of life?

As we discovered more about the natural world… not all organisms fit into Linnaeus’s 2 kingdoms (_____ or _____) Ex: _________ _____ Images from: plant animal bacteria fungi

THREE-DOMAIN system Molecular analyses have given rise to a ___________ _______ now recognized = _______ DOMAIN new taxonomic category

Domains are larger than Kingdoms and are based on the kind of ____________ an organism has. EubacteriaArchaebacteriaProtistaPlantaeFungiAnimalia Bacteria Archaea Eukarya Ribosomal RNA

Kidspiration by Riedell 6 Kingdom System PlantaeFungiProtista EubacteriaArchaebacteria Animalia

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 = _____________ REMEMBER PROKARYOTE EUKARYOTE AUTOTROPH HETEROTROPH

A ONE-CELLED organism = _____________________ Organism made of many cells = ______________ Polysaccharide made by joining glucose molecules together which makes plants sturdy = _________________ REMEMBER UNICELLULAR MULTICELLULAR CELLULOSE

What are the two broadest categories of the classification system???? Domain Kingdom How many domains are there?

3 Domains 1. Bacteria 2. Archea 3. Eukarya

Domains are based on the characteristics of 1. Cell Type 2. Cell Structure What are the 2 cell types again???

Domains Archaea and Bacteria are made up of unicellular prokaryotes Eukarya are made up of multicellular and unicellular organisms that have eukaryotic cells.

The difference between Domain Bacteria and Domain Archaea is the cell structure. Domain Bacteria - the cell wall is made up of peptidoglycan. Domain Archaea - the cell wall DOES NOT have peptidoglycan

Polymer made of sugars and amino acids found outside the cell membrane in the cell wall in some bacteria = ______________ PEPTIDOGLYCAN

Peptidoglycan=Cell wall component.

Quick check!! What are the 3 Domains? Bacteria are made up of what kind of cells? Eukarya are made up of what kind of cells? What's the difference between Domain Bacteria and Domain Archaea?

How many kingdoms are there???

6 kingdoms BrainPOP

3 Domains 6 Kingdoms

DOMAIN: BACTERIA KINGDOM: EUBACTERIA _______________________ ______________________ Have cell walls with ________________ Can be ____ ____________ or ______________ EXAMPLES: _____________________ PROKARYOTES PEPTIDOGLYCAN UNICELLULAR AUTOTROPHS HETEROTROPHS E. coli, Streptococcus

DOMAIN: ARCHAEA KINGDOM: ARCHAEBACTERIA _________________ Have cell walls _________ peptidoglycan Can be___ ___________ or ______________ EXAMPLES: _____________________ LIVE IN EXTREME ENVIRONMENTS like volcanic hot springs, brine pools, low oxygen PROKARYOTES WITHOUT UNICELLULAR AUTOTROPHS HETEROTROPHS Halophiles; thermophiles;

Organisms that can live in HIGH temperature environments = ________________ Organisms that can live in high salt environments = ______________ HALOPHILES THERMOPHILES

What are the kingdoms of Eukarya??? 1. Protista 2. Fungi 3. Plantae 4. Animalia

DOMAIN: EUKARYA KINGDOM: PLANTAE _______________________ ______________________ Have cell walls with ________________ and _____________ _________________ EXAMPLES: _____________________ EUKARYOTES CELLULOSE MULTICELLULAR AUTOTROPHS Mosses, ferns, trees, flowering plants CHLOROPLASTS

DOMAIN: EUKARYA KINGDOM: ANIMALIA _______________________ _____________________ ________________ or _______________ __________________ EXAMPLES: _____________________ EUKARYOTES NO CELL WALLS CHLOROPLASTS MULTICELLULAR HETEROTROPHS Worms, insects, fish, birds, mammals, humans

DOMAIN: EUKARYA KINGDOM: FUNGI _______________________ ______________________ Have cell walls with ________________ _______________ EXAMPLES: _____________________ EUKARYOTES CHITIN Most MULTICELLULAR; few UNICELLULAR HETEROTROPHS- absorb nutrients from decaying organic matter Mushrooms, yeast

DOMAIN: EUKARYA KINGDOM: PROTISTA _______________________ ______________________ Some have cell walls with ________________ ____________________ Can be _____________ or _____________ EXAMPLES: _____________________ EUKARYOTES CELLULOSE Most UNICELLULAR; some colonial/multi Some have chloroplasts AUTOTROPHS HETEROTROPHS Amoeba; Paramecium; Giant kelp; slime mold

Viruses Are they alive?? Viruses are not living so they are not placed in the classification system.
