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
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 -
Cell Type Eukaryote
Cell Number Unicellular & Multicellular
Nutrition Autotrophs and Heterotrophs
Example Paramecium, Euglena, Amoeba, Algae, Kelp
Special Information Lacks complex organ systems Lives in moist environments
Cell Type Eukaryote
Cell Number Multicellular & Unicellular (Yeasts only exception)
Nutrition Heterotrophs
Example Mushrooms, molds, yeast
Special Information Have a cell wall Decompose large quantities of Earth’s organic waste
Cell Type Eukaryote
Cell Number Multicellular
Nutrition Autotrophs
Example Mosses, coniferous trees, deciduous trees, flowering plants
Special Information Photosynthesis provides almost all the oxygen in Earth’s atmosphere
