Why are the
The Brown SquirrelWhat are
mammals you just

other
gave NOT part of
examples of
this order?
Kingdom (Animalia, or "animal")
mammals?
Phylum (Chordata, or "has a backbone")
Class (Mammalia, or "has a backbone and nurses its young")
Order (Rodentia, or "has a backbone, nurses its young, and has long, sharp front teeth)

  Family (Scuridae, or "has a backbone, nurses its young, has long, sharp front teeth, and has a bushy tail)

  Genus ( Tamiasciurus , or "has a backbone, nurses its young, has long, sharp front teeth, has a bushy tail, and climbs trees)

  Species ( hudsonicus , or "has a backbone, nurses its young, has long, sharp front teeth, has a bushy tail, and has brown fur on its back and white fur on its underparts)

 

 

 

 

  Binomial nomenclature

  Each organism is assigned a 2-part Latin
name.

  E.g.

Carl Linnaeus

  Castor canadesis

  beaver from canada

  Homo sapien?

  Taxonomy: The Classification of living
organisms.

  Dichotomous Keys

  A tool used to identify species based on their
physical characteristics.

  Constructed as a series of choices (2 choices)
leading to new branches of other choices,
narrowing the organism down to a specific
species.

Let s try!

  Alien Dichotomous Key

  Owl Pellets

Kingdom Archaebacteria

  Prokaryotic

  Heterotrophs

  Bacteria that live in extreme conditions

  e.g. Bacteria in volcanoes

Methanogens

Extreme halophiles

Extreme thermophiles

Kingdom Eubacteria

  Simple organisms lacking nuclei
(prokaryotic)

  Either Heterotrophs or autotrophs

  Can reproduce asexually

  Bacteria that are found everywhere

  E.g. E. coli

Kingdom Protista

  Found many places, some terrestrial, mostly
aquatic

  Some have chloroplasts

  Most are single celled; some are multicellular
organisms; some are eukaryotic

  Some are autotrophs, some Heterotrophs, some
both

  Reproduce sexually and asexually

  e.g. Amoeba, Paramecium

Kingdom Fungi

  Similar to plants but

unable to carry out
photosynthesis

  Heterotrophs

  Most are multicellular

  Have cell walls but
not made of cellulose

  Reproduce sexually
and asexually

  Most are terrestrial

  e.g. Yeasts, moulds,
mushrooms

Kingdom Plantae

  Cell walls contain
cellulose

  All are multicellular

  All are autotrophs *

  Most reproduce
sexually and
asexually

  Have chloroplasts

  e.g. Mosses, ferns,
seed plants

Kingdom Animalia

  Cells do not have cell

walls
All are multicellular
All are Heterotrophs
Reproduce sexually
Live in terrestrial and
aquatic habitats

  Includes invertebrates (no
backbone) and
vertebrates (have
backbone)

  e.g. Clam, fish, turtle, cat,
human
