Taxonomy Flashcards
Extremophiles
Organisms that live in extreme environments
Domain Archaea
List the 3 Domains
Bacteria
Archaea
Eukarya
Domain Bacteria
Single celled prokaryotes
Autotrophic or heterotrophic
Conjugation
primitive form of sexual reproduction carried out by some bacteria
Domain Archaea
Extremophiles
Unicellular
Prokaryotic
Methanogens
Produce methane from hydrogen
An extremophile
Halophiles
High salt concentrations
Extremophile
Thermophiles
thrive in high temperatures
extremophile
Four kingdoms of the domain Eukarya
Protista
Fungi
Plantae
Animalia
Kingdom Protista
Widest variety
Eukaryotes
Heterotrophs and autotrophs
Move by various means
Ex: Amoeba and Euglenas, seaweeds, slime molds
Kingdom Fungi
Heterotrophic eukaryotes
Uni or multi cellular
Extracellular digestion
Saprobes
Sexual reproduction
CHITIN makes cell wall
Ex: Lichens, yeast, mold, mushrooms
Saprobes
Organisms that obtain food from decaying matter
Fungis
Kingdom Plantae
Autotrophic eukaryotes
Photosynthesis
Kingdom Animalia
Multicellular, heterotrophic eukaryotes
Sexually
Ex: Humans
Sponges
Loose federation of cells
Not considered tissue because too unspecialized
Cnidarian
Hydra and jellyfish
Polyp or medusa body shape
All have stingers
Germ layers
The main layers that form various tissues and organs of the body
Ectoderm
Outermost germ layer
Becomes the skin and nervous system
Endoderm
Deep Germ layer
Becomes the digestive system
Mesoderm
Middle germ layer
Becomes the blood muscles and bones
Radial symmetry
primitive animals exhibit
Bilateral symmetry
sophisticated animals exhibit
Acoelomates
like earthworms with a flat body cavity
Pseudocoelomates
like roundworms, they have a fluid filled tube that acts as a hydroskeleton
Coelomates
most complex body cavity
has a coelom
Porifera
Sponges
Sessile (do not move)
no symmetry
Platyhelminthes
Flatworms
Simplest animals
Exchange nutrients through diffusion
Nematodes
Roundworms
Parasitic
Annelids
Earthworms, leeches
Mollusks
Squids, octopuses, slugs, clams, and snails
Soft body with hard shell
Bilaterial symmtry
Anthropods
Grasshopper, crustacea, arachnida (spider)
Have head, thorax, and appendage
Echinoderms
Sea stars and sea urchins
Sessile (cant move) or slow
Endoskeleton
Chordates
Fish, amphibians, reptiles, birds, mammals
Notochord (rod that is a flexible axis)
Homeotherms
Maintain a constant body temperature
Ex: birds and mammals
Endotherms
Can raise their body temperature from within
Ex: birds, mammals
Ectotherms
Cold blooded
Ex: reptiles and most fish
Chordata
The phylum that mammals belong to
Primate
Monkeys, apes, humans
that Lucy video we watched
CHITIN
Makes fungi cell wall
