Archaea

1
Archaea

• Domain belonging to archaebacteria.
• Prokaryotic organisms
• Contains many extremophiles organisms that
  thrive in extreme environments
• Thermophiles hot environments like geysers and
  thermal vents in the ocean floor
• Halophiles extremely salty environments (Dead
  Sea)
• Methanogens environments like the gut of cows

2
Bacteria

• Domain containing prokaryotic organisms.
• Bacteria can be heterotrophic or autotrophic
  (chemotrophic or phototrophic)
• Perhaps the largest group of organisms in
  existence
• Some can be pathogenic
• Classified by shape, color and the makeup of
  their cell walls.

3
Eukarya

• Domain containing eukaryotic organisms.
• Made up of 4 kingdoms
• Animalia
• Plantae
• Fungi
• Protista
• Contains both unicellular and multicellular
  organisms.

4
Animalia

• Multicellular, eukaryotic organisms
• Heterotrophic
• Motile for at least a portion of their lives
• Phyla include
• Porifera Mollusca
• Cnidaria Tardigrada
• Platyhelminthes Arthropoda
• Nematoda Echinodermata
• Annelida Chordata
• Bryozoa

5
Plantae

• Eukaryotic, multicellular organisms
• Autotrophic, producing food by photosynthesis.
• Unlike animals, they have cell walls.
• Generally sessile (not moving)
• Organisms include
• Angiosperms (flowering plants)
• Conifers (cone-bearing)
• Ferns
• Mosses

6
Fungi

• Multicellular or unicellular eukaryotes
• Heterotrophic, generally decomposers
• Like plants, have a cell wall, but theirs
  contains a polysaccharide called chitin.
• Some are pathogenic.
• Members include
• Mushrooms
• Molds
• Yeast

7
Protista

• Eukaryotic and generally unicellular
• Some protists are animal-like
• Protozoa
• Amoeba
• Paramecium
• Euglena
• Some protists are plant-like
• Algae
• Some protists are fungus-like
• Slime molds

8
Porifera

• Phylum in the kingdom Animalia
• Sponges
• Sessile adult form, but motile larvae
• Filter feeders
• Dont have digestive, nervous, or circulatory
  systems

9
Cnidaria

• Phylum in the kingdom Animalia
• Jellyfish, anemones and corals
• Some are motile and others are primarily sessile.
• Many have radial symmetry

10
Arthropoda

• One of the largest phyla in kingdom Animalia
• Insects, Arachnids, Crustaceans, etc.
• Have an exoskeleton that contains chitin.
• Segmented bodies
• Open circulatory system

11
Chordata

• Another large phyla of kingdom Animalia
• Chordates are unique in that they have a spinal
  cord (but not always a backbone).
• Representative groups
• Mammals
• Reptiles
• Amphibians
• Fish
• Birds
• Tunicates (sea squirts)

12
Mammalia

• Endothermic (warm-blooded) chordates
• Possess hair and a neocortex (region of the
  brain)
• Females produce milk for young
• Give birth to live offspring with the exception
  of monotremes (platypus and echidna)
• Contains the largest animals (whales) and the
  most intelligent (apes)

13
Reptilia

• Terrestrial (land-dwelling) chordates
• Cold-blooded (ectothermic)
• Lay amniotic eggs
• Possess scales
• Members include
• Lizards Turtles
• Snakes Tuataras
• Crocodiles

14
Fish

• Paraphyletic group, meaning that fish come from
  multiple phyla.
• Gill-bearing aquatic animals
• Lack limbs with digits (fingers)
• Mostly ectothermic (cold-blooded), but some can
  maintain warmer body temperatures.
• Lay an external, non-amniotic egg.

15
Aves

• Class of chordates made up of birds
• Endothermic (warm-blooded), egg-laying
• Have feathers and a beak with no teeth
• Four-chambered heart
• Strong, but lightweight skeleton
• Most are capable of flight, except for
• Ratites (ostriches, emus)
• Penguins
• Some other island species

16
Amphibia

• Cold-blooded class of chordates
• Lay eggs in water
• Larvae (tadpoles) are aquatic, but undergo
  metamorphosis to live on land as adults
• Use skin as a secondary respiratory surface
• Three chambered heart
• Includes
• Frogs Salamanders Newts
