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
