Term
taxonomy
Definition
classification and nomenclature of organisms
Term
what is the modern classification technique
Definition
evolutionary techniques
Term
what are the kingdoms
Definition
viruses,monera,protista,fungi,plantae,animalia
Term
order of classification
Definition
kingdom,phyla/division, subphyla/subdivision,classes,orders,families,genera,species(able to reproduce a similar offspring)
Term
nomenclature
Definition
naming based off Genus species….Homo Sapien
Term
what is the alternate kingdoms
Definition
includes monera, plantae(w/fungi), animalia(including protista)
Term
viruses
Definition
not considered living, depends on hosts reproductive machinary to replicate
Term
monera
Definition
prokaryotes aka bacteria, reproduce asexually, no nucleus membrane…important role in biochemical cycles
Term
protista
Definition
eukaryotic organisms with both plant and animal characteristics
Term
fungi
Definition
nonphotosynthetic plants, mutlicellular, differentiated, nonmotile, either saprophytic(off of dead organic) or parasitic, they absorb their enviroment
Term
difference btween plant and fungi cell wall
Definition
fungi cell wall is made out of chitin…plant has cellulose
Term
how are viruses varied
Definition
either RNA or DNA, either bacteriophages or not, lytic or lysogenic
Term
cyanobacteria
Definition
aka blue-green algae that can photosyntheisez via pigments, but still prokaryotic, can handle extreme temperature
Term
how are bacteria diverse
Definition
morphological differences (cocci-round, bacci-rods, spirilla-spiral, di-duplexes, staph-clusters, strep-chains)…and biochemical pathways
Term
protozoa
Definition
a type of protist-heterotrophic single cells…include rhizopods(ameobas), and ciliophors(cilia for feeding and moving)
Term
algae
Definition
photosynthetic protist..include phytoplankton, Euglena(can also act as flagellum)
Term
slim molds
Definition
protist(algae) + fungi which are coenocytic(multinucleus), reproduce asexually by sporulation
Term
in general how do animal ingest and digest
Definition
all except some parasite, ingest bulk foods (holotrophic), digest, and eliminate the remains
Term
sessile
Definition
stationary organisms
Term
sponges
Definition
2 cell layers, sessile, low degree of cell specilization
Term
Cnidarians
Definition
one opening digestive tract, 2 layers (ecto and endoderm), tentacles, stinging cells, net nerves
Term
Platyhelminthes
Definition
flat worms: ribbon like, bilateral symerty, SOLID mesoderm, no circulitory, nervous system with eyes and anterior brain gnaglion, lingitudinal nerve cords
Term
Nemotoda
Definition
Round worms: long digestive tubes, sold mesoderm, no circ system, nerve cords and nerve ring includes hookworm, trichina
Term
Annelida
Definition
segmented worms: with a coelom(true body cavity) in the mesoderm, good nervous circ&excretory systems includes earthworms and LEECHES
Term
Mollusca
Definition
soft bodied and has mantles secrete calcium carbonate exoskeletons, breathe by gills and contain chambered hearts, blood sinuses, pair of ventral nerve cords. CLAMS, snail, squids
Term
Arthropods
Definition
jointed appendeges, chitinous exoskelton, and open circulatory system,,,(insects-6 legs tracheal tubes for breathing,,,,,arachnifd-8 legs and book lungs,,,Crustasceans-varied number of legs has gills)
Term
Echinoderms
Definition
spiny, radically symetrical, water vascular system, regeneration of parts, related to chordates
Term
Chordates
Definition
notochord-at embryo development, gill slits, tail beyond development (sometime in life or embryo life)
Term
what are chordates but not vertebrates
Definition
lancelets and tunicates
Term
Fish
Definition
2C Hearts, gills, external fertilization
Term
Jawless Fish
Definition
eel like, notochord all life, internal cartilage, no jaws, sucking mouth, Agnatha, lamprey and hagfish
Term
Cartilaginous Fish
Definition
fish with jaws and teeth, reduced notochrods in segments between cartilg vertebrate..like shark or sting ray
Term
bony fish
Definition
most common fish, scales, lost notochord as an adult, bony skeleton replaces catilage, stugeon, trout, tuna
Term
Ampibian
Definition
larval stage called tadpole(on water,gills,no legs,tail), adult life on land with legs,lungs,no tail,3C heart,external fertilization(jelly like)
Term
Reptiles
Definition
terrestrial animals, lungs, leathery eggs, internal fertilization, cold blooded(poikilothermic), scales, 3C heart (turtles,lizard,snake,crocdile)
Term
Birds
Definition
4C heart, warm blooded, eggs with shells
Term
monotremes
Definition
mammals with leathery eggs, horny bills, milk with no nipples (duckbill platypus, spiny anteater)
Term
marsuipials
Definition
pouched, completes development while attached to nipples in the abdominal pouch
Term
placental mammals
Definition
fully developed in uterus
