Used to show relationships between organisms ◦ Shows who evolved first (based on geologic history)

◦ Shows which organisms are either very closely related or distantly related

Archaebacteria, Eubacteria, Protista, Fungi, Plantae, Animalia

Eukaryote ◦ Multi-cellular organisms which contain a true

nucleus and membrane-bound organelles

Prokaryote ◦ Uni-cellular organisms that lack internal

membrane-bound structures

Autotroph ◦ Organisms that use energy from the sun or energy

stored in chemical compounds to manufacture their own nutrients

Heterotroph ◦ Organisms that cannot make their own food and

must feed on other organisms for energy and nutrients

Unicellular ◦ Organism made up of only one cell

Multicellular ◦ Organisms made up of more than one cell

Cell Type Prokaryote

Cell Number Unicellular

Nutrition Autotrophs and Heterotrophs

Example Methanogen bacteria, thermophiles, halophiles

Special Information Live in extreme environments – thermal vents, salt lakes, no oxygen, highly acidic environments

Cell Type Prokatyote

Cell Number Unicellular

Nutrition Autotrophs and Heterotrophs

Example Probiotics (yogurt and cheese), staphylococcus, streptococcus, salmonella

Special Information Eu = true Most are helpful More in your body than people in the world Gram + & Gram -
