Eubacteria

Archaebacteria

Eukaryotic

Three Types of Domains

Eubacteria Archaebacteria Eukaryotic

Prokaryotes (No Nucleus)

Eukaryotes (Nucleus)

Eubacteria u Everywhere on Earth (soil, water,

live in or on other organism) u Tiny Single cell u No nucleus u No membrane bound organelles u Bacteria DNA – loop u Has a Cell wall u Round, Rod, or Spiral shaped u Can cause diseases u Used to make yogurt and pickles

Eubacteria

Eubacteria

Archaebacteria u  Live in places where most bacteria Can

Not live u Tiny Single cell u No nucleus u No membrane bound organelles u Circular DNA – loop u Cell wall of different materials u 3 Types –

(1)“Heat loving” (Hot Springs) (2) “Salt loving” (Oceans) (3)“Methane making” (Methane is a gas usually found in swamps)

Archaebacteria “Salt Loving”

Archaebacteria “Heat Loving”

u Archaebacteria u “Methane Making”

Eukaryotic u  Found on All Continents u  Largest cells – can see cell without

microscope u Multicellular organisms (many celled) –

some single cell u Have a Nucleus u Have Membrane bound organelles u DNA in Nucleus u Cell wall in plants only

u Examples: animals, plants, algae, fungi, yeasts

Eukaryotic

Eukaryotic

Two Groups

u Prokaryotes – No Nucleus – Example – – Eubacteria – Archaebacteria

u Eukaryotes – Have a Nucleus

– Example – – Eukaryotic
