Taxonomy

Carl von Linnaeus

  • Physician & Botanist
  • Classified into 3 kingdoms
    • Plants
    • Animals
    • Fungi
carl von linnaeus
Created uniform naming system

- binomial nomenclature

- Homo sapiens

- Canis lupus familiaris (domestic dog)

History of Taxonomy

Carl von Linnaeus
5 kingdoms of classification
5 Kingdoms of Classification
  • Monera – one-cell, no organized nucleus (bacteria)
  • Protista – one-cell, organized nucleus (amoeba)
  • Fungi – multi-cellular, feed on decay, (mushrooms)
  • Plantae – all require sunlight (Azalea)
  • Animalia – ingest nutrients (dog)
unicellular vs multi cellular
Unicellular vs. Multi-cellular

Are they ……

  • Unicellular
    • one cell
  • Multi-cellular
    • many cells
prokaryotic vs eukaryotic
Prokaryotic vs. Eukaryotic

Are they…..

  • Prokaryotic –
    • no membrane bound nucleus (Monera)
  • Eukaryotic
    • membrane bound nucleus (Protista)
  • Pro’s have no; Eu’s do
symmetry
Symmetry

Do they have . . . .

  • Bilateral Symmetry
    • each half a mirror image
    • all mammals
  • Radial Symmetry
    • parts arranged around central point
    • star fish; most plants
symmetry1
Symmetry
  • Asymmetrical
    • not symmetrical
    • fiddler crabs
coelomates vs acoelomates
Coelomates vs. Acoelomates

Are they . . . .

  • Acoelomates – not have hollow body cavity
    • Flat worms
  • Coelomates – have hollow body cavity
    • Earthworm
    • Humans
segmentation
Segmentation

Are they . . .

  • Segmented –
    • humans
    • insects
  • Non-segmented
    • worms
homeotherm vs poikilotherm
HomeothermvsPoikilotherm

Are they . . .

  • Homeotherms – warm blooded; constant body temp
    • Mammals
    • Birds
  • Poikilotherm – cold blooded; body temp same as environment
    • Reptiles
    • Amphibians
    • Most fish
motile vs sessile
Motile vs. Sessile

Are they . . .

  • Motile – capable of moving
  • Sessile – not capable of moving
vertebrates vs invertebrates
Vertebrates vs. Invertebrates

Are they . . .

  • Vertebrates – backbone
    • Mammals
    • Birds
    • Fish
  • Invertebrates – no backbone
    • Jellyfish
    • Snails
    • Insects
open vs closed circulatory system
Open vs Closed Circulatory System

Do they have . . .

  • Open – no true heart or blood vessels
    • Insects
    • Mollusks
    • Invertebrates
  • Closed – blood vessels
    • Vertebrates
  • Types of Circulatory Systems
sexual vs asexual
Sexual vs Asexual
  • Asexual
    • Budding, fission
    • Produces identical offspring to parent
  • Sexual
    • Male and female gametes unite
    • Produces characteristics from both parents
internal vs external fertilization
Internal vs. External Fertilization
  • Internal
    • Sperm and egg unite inside the female
  • External
    • Female lays eggs
    • Male fertilizes
feeding
Feeding
  • Carnivore – meat only
  • Herbivore – plants only
  • Omnivore – both
autorophic heterotrophic
Autotrophs

can make their own food

photosynthetic plants and chemosynthetic organisms.

Heterotrophs

cannot make their own food

undergo cellular respiration

Autorophic/Heterotrophic

species sapiens
Species: Sapiens
  • modern man
  • longer legs, leaner bodies
