Transcript Biological Classification - Sebastian Charter Junior High

Biological Classification
Domains
• 3 Domains
• Most inclusive or broad groups
»Prokaryotes
1)Bacteria (true bacteria)- found everywhere
2)Archaeabacteria (extreme bacteria)- found
in extreme conditions, related to ancient
bacteria
3)Eukaryotes
Kingdoms
• Large groupings of living things based on
characteristics they have in common
– Ex: the way they obtain food is a characteristic
that is used to group the 4 kingdoms
– Protista (single celled)
–Fungi (decomposers) (multicellular)
–Plantae (make their own food) (Autotrophs)
–Animalia (depend on others for food)
(Heterotrophs)
Kingdom Archaeabacteria
•
•
•
•
•
•
•
Extreme environments
Can even survive the absence of Oxygen
Contain unusual lipids in cell wall (capsule)
Unicellular
Autotrophic or Heterotrophic
Reproduce Asexually
Ex: Thermophiles or Halophiles
Kingdom Bacteria
•
•
•
•
Unicellular
Some Perform Photosynthesis (Autotrophic)
Some are Heterotrophic
3 shapes
Kingdom Protista
•
•
•
•
•
Eukaryotic Single Celled
Some do photosynthesis
Some are heterotrophic
Most reproduce Asexually Binary fission
Ex: Algae, Amoeba, Paramecium
Kingdom Fungi
•
•
•
•
Eukaryotic Multicellular (Mostly)
Heterotrophic Decomposers
Cell walls made of Chitin
Reproduce Asexually or Sexually
Kingdom Plantae
• Multicellular Eukaryotic
• Autotrophic
• Phyla: Conifer, Angiosperm, Mosses, Ferns
Animal Kingdom
• Multicellular Eukaryotic
• Heterotrophic
• Lots of Diversity
Within the Kingdoms

Phylum
Class
Order
Family
Genus
Species
Each category gets more exclusive using
characteristics that each group has in common
Focus on Kingdom Animalia
• The Phyla are….
–
–
–
–
–
–
–
–
–
Sponges
Cnidarians
Flat Worms
Round Worms
Moluska
Annelids
Arthropods
Echinoderms
Chordates (Vertebrates and Tunicates and Lancelets)
Focus on Kingdom Animalia
• Classes of Animals are…
– Reptiles
– Amphibians
– Aves (birds)
– Fish
– Mammals
*These are all included from the phylum Chordata
Focus on Kingdom Animalia
• Orders are….
• Ex: Within the Class of Mammalia you have 12
Orders
– Insectivores
– Rodents
– Primates
– Artiodactyls
– Cetaceans……………..
Most Closely Related of All…
• Family, Genus, and Species are within the
orders
– They are the most exclusive categories of all!
– They share the most characteristics than any other
category
– The Genus and Species make up the animals
scientific name
•
•
•
•
Binomial (2 names)
Italicized or underlined
Genus is 1st and capitalized
Species comes 2nd and is lower cased
