Taxonomy & Bacteria

AP Focus 6 Kingdom Survey

QuestionAnswer
Father of Taxonomy Carolus Linnaeus
Developed system of binomial nomenclature Carolus Linnaeus
Binomal nomenclature each species given a two part name using genus and SPECIFIC EPITHET ex. Canis familiaris (italicized)or C. familiaris (underlined)
SPECIFIC EPITHET second part of name
Taxanomic hierarchy Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species ("Did King Phil Call Out For Good Spaghetti?")
How organisms are classified Phylogeny (evolutionary relationships) and the study of those is called systematics
Bacteria used to be classified in this kingdom Monera
Bacteria now classified into two kingdoms called this Bacteria and Archaea
DIFFERENCE B/T BACTERIA AND ARCHAEA ARCHAEA LACKS THE CELL WALL COMPONENT PEPTIDOGLYCAN
Cocci Round
Bacilli Rod
Spirilli Spiral
Flagella Made of flagellin looped in helical coils
ENDOSPORE HELPS BACTERIA SURVIVE UNFAVORABLE CONDITIONS
Autotrophs Bacteria that use photosynthesis (sunlight) or chemosynthesis (hydrogen sulfie, ammonia, nitrate, or nitrite) to make organic compounds
Heterotrophic Bacteria that function as harmless decomposing organisms (saprobes) or harmful parasites
Obligate aerobes Bacteria that can only live in oxygenated environments
Obligate anaerobes Bacteria that oxygen will kill
Falcultative Anaerobes Bacteria that can live in oxygen or switch to anaerobic metabolism when oxygen isn't availabe
Domain Archaea lack peptidoglycan, have RIBOSOMES, live in extreme environments (X-GAMES)
Methanogens Archaebacteria that are anaerobic and found in swamps, mud, and the guts of animals (such as humans) and produce methane
Halophiles Archaebacteria that are "salt loving", most are aerobic heterotrophs but the anaerobic photosynthetic halophiles have a special photosynthetic pigment called bacteriorhodpsin
Thermoacidophiles Achaebacteria that live in temperature or acidity extremes and can be found in areas such as hot springs or deep ocean hydrotherman vents where they use H2S as an energy source for chemosynthesis
Domain Bacteria grouped by mode of nutrition gram-staining
Gram-staining series of dyes that stain thick peptidoglycan cell walls (gram-positive), those that don't retain the stain (gram-negative)
CYANOBACTERIA Eubacteria, BLUE-GREEN ALGAE CHANGED ATMOSPHERE BY ADDING OXYGEN
Nitrogen fixing bacteria helps convert N2 gas into usable formats for other organisms

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
