AP Bio: Focus 1

QuestionAnswer
Who is considered the father of taxonomy? Carolus Linnaeus
What is binomial nomenclature? genus and specific epithet
What is the taxonomic hierarchy? Domain, Kingdom, Phylum, Class, Order, Family, Genius, Species
Systematics The study of organisms classified by phylogeny
Phylogeny Evolutionary relationships
Archaea & Bacteria are (unicellular/multicellular) Unicellular
Archaea & Bacteria are (prokaryotic/eukaryotic) prokaryotic
Archaea & Bacteria lack what a nucleus and ribosomes
cell wall component that Archaea and bacteria lack ribosomes
plasmids additional loops of DNA
Archaea & Bacteria have a large single chromosome in the neucleoid region
3 main shapes of bacteria cocci, bacilli, spirilla
endospore jelly-like capsule coating containing the neucleoid and a small amount of cytoplasm to survive when conditions become unsuitable
bacteria&arachaea are mostly(autotrophs/heterotrophs) autotrophs
bacteria&archaea uses BLANK or BLANK to make organic compounds photosynthesis, chemosynthesis
saprobes harmless decomposing bacteria
obligate aerobes need oxygen
obligate anaerobes can't have oxygen
facultative anaerobes can live in oxygen but they can survive if there is none available
Domain archaea lack this peptidoglycan, cell wall component
Domain Archaea's ribosomes are more akin to BLANK than Domain Bacteria eukaryotes
Domain Archaea lives in extreme environments
3 main groups of domain archaea methanogens, halophiles, and thermoacidphiles
methanogens D:A, anaerobic, found in swamps, mud, and guts of animals, produce methane
halophiles salt loving, most aerobic heterotrophs, D:A, anerobic photosynthetic halophiles have bacteriorhodpsin
bacteriohodpsin a special photosynthetic pigment
thermoacidphiles live in temperature or acidity extremes, found in hot springs or deep ocean D:A, hydrothermal vents where they use H2S as an energy source for chemosynthesis
Domain bacteria is grouped by nutrition and gram staining
what does gram staining stain peptidoglycan cell walls
Eubacteria groups include cyanobacteria, nitrogen fixing bacteria
cyanobacteria D:B, photosynthetic, were first group to add O2 to the atmosphere
nitrogen fixing bacteria D:B, help 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.
