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)


Monera bacteria protista

Taxonomy

  • Classification and Naming of Living Things Review


Characteristics used to classify organisms

Characteristics Used to Classify Organisms


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
