Kingdoms and Ecology Flashcards
Domains
Archean, Bacteria, Eukaryotes
Cladogram
a phylogenetic diagram that specifies unique features
Archaea
Ancient extremphiles with different cell wall and have histones like eukaryotes but prokaryotes
Bacteria
unicellular, prokaryote, reproduce by binary fission
Eukaryote
plants, animals, fungus, protista
bipedal
walk on two feet
cerebrum
brain; larger in primate order. 370 cc vs 1300cc
primates
order; humans & apes in
opposable thumb
able to fully grip and hold things….
hominid
genus;
Australopithecus
genus;
H. habilis
2.2-1.5 mya; lived in Tanzania; brain 550cc or more; Richard Leakey discovered skeleton & found flake tools with it
H. erectus
hairless, more human-like, sweat glands, 1.6my-700000, found from Asia to Africa, 800cc brain, flake axe, fire pits(fire from environment)
Neanderthals
130000-30000 years ago, Europe-Asia, 1400cc brain 5ft tall, “cavement” spears/flake tool, furs, war?, burried dead, took care of each other
cocci
round shaped bacteria
bacillus
rod shaped bacteria
spirilla
spiral shaped bacteria
binary fission
asexual reproduction that doesn’t use spindle fibers
bacterial conjugation
pass plasmid through mating bridge (pili)
antibiotic
bacteria has different cell wall and ribosomes so the antibiotic destroy those without destroying our cells
extremophile
loves extreme environments; halophile live in high salt concentrated areas like the Dead sea; thermophiles like hot climate such as hot springs
chemoautotroph
use chemicals like nitrites and H2S for energry ex. archaea in dark
photoautotroph
use light like plants to make food
chemoheterotroph
get energy by eating organic food
obligate anaerobe
dies when exposed to O2 (tetanus)
obligate aerobe
dies without O2
Protozoa
Animal like Protista; unicellular heterotrophs.
Ex. Paramecium, amoeba, malaria
Why we shouldn’t drink water in foreign countries
Algae
Plant like Protista; make up to 70% of the O2 we breathe; important as food; commercially used (thickens makeup, etc)
Slime mold
Fungi like Protista; unicellular & multicellular stages; don’t do photosynthesis eat & reproduce like mushrooms
Paramecium
Animal like Protista…
Amoeba
Animal like Protista
Fungus
Heterotrophic decomposers Structure: Mycelium- the long continuous thread of fungus cells; made of hyphae Reproduction: asexual spores Cell wall made of chitin
Uses: bread (yeast), diet (truffles, etc.), fungus (antibiotics, used to kill bacteria)
Problems: ergot-grows on grain/destroys crops, rot crops, yeast & other infections, nail infections, athletes foot
Plantae
Cellulose cell wall, photosynthesis, sexual, multicellular
