Classification Scheme
How many kingdoms?
Lumpers v. Splitters 5 Kingdoms: Monera (now archaebacteria & eubacteria), Protista, Plantae, Fungi, Animalia
6 Kingdoms: Eubacteria, Archaebacteria, Protista, Plantae, Fungi, Animalia
8 Kingdoms: Eubacteria, Archaebacteria, Archenzoa, Chromista, Protista, Plantae, Fungi, Animalia
Virus? Where does it fit in?
A Virus treads the fine line that separates living and nonliving things Viruses need a host cell (bacteria, plant or animal) to live in and reproduce Ex: AIDS, Herpes, Hepatitis C, Smallpox, West Nile Virus, Ebola. SARS, Flu, Foot & Mouth Disease
Archaebacteria
Domain: Archaea Prokaryotes Unicellular Have Cell Walls Autotrophic or Heterotrophic Anaerobic (does not require oxygen) EX: Halophiles/ Thermophiles/ Methanogens
Eubacteria
Domain: Bacteria Prokaryote Unicellular Has Cell Walls Autotroph or Heterotroph Aerobic or anaerobic Examples: e coli, strep, cyanobacteria, Treated with antibiotics
Protists
Domain: Eukarya Eukaryotic Both Unicellular and Multicellular Some have cell walls Both Heterotrophic and Autotrophic Aerobic Examples: Amoeba, Euglena, Volvox, Algae
FUNGUS
Domain: Eukarya Decomposers Eukaryotic Both Unicellular and Multicellular Cell walls made of chitin Heterotrophic Aerobic Examples: Next page
FUNGUS
Decomposers Common Molds: Mildew, Bread mold Sac Fungi: Yeast, Powdery Mildew Club Fungi: Mushrooms Imperfect Fungi: Athletes Foot, Ringworm
Plant Kingdom general characteristics Domain: Eukarya Eukaryotic Mutlicellular Cell walls made of cellulose Autotrophic Aerobic
Plant Kingdom general characteristics Has 12 major DIVISIONS
The plant kingdom uses divisions rather than phyla
Plants have three main parts Roots: anchor plant Stems: transport materials Leaves: site of photosynthesis (in chloroplasts) MAKES THE FOOD!!
Examples: next page
Non-vascular Divisions Liverwarts Hornwarts Mosses Small, low to the ground MUST have moisture to reproduce Decomposer
Vascular W/O seeds Whisk Ferns Club Mosses Horse Tails Ferns Largest group of vascular plants Alternation of generations
Vascular With Seeds Gnetae Cycads Ginkgoes Have male and female trees Conifers (gymnosperms) Grow very large & old Have needles and cones
flowering plants
Have flowers Produce Fruit Large variety
The Animal Kingdom
Domain: Eukarya Eukaryotic Multicellular NO cell walls Heterotrophic Aerobic Examples: Next pages
Porifera/Sponges
Sponges
Lack Specialized Tissues Filter Feeders Sessile (cannot move) Asymmetry Environmental Indicators
Cnidarians
Stinging Cells Radial Symmetry Examples: Coral, hydra, sea anemone, jelly fish
Platyhelminthes-Flatworms
Bilateral Symmetry Unsegmented/Flat EX: Planarians, Tapeworms & Flukes
Nematoda-Roundworms
Round, Unsegmented bodies Ex: ascaris(hookworms & pinworms), wuchereria bancrofti
Mollusks
EX: Snails, slugs, Scallops & Squids Soft body protected by a hard shell Mantle, Foot & Visceral Mass
Annelids-Segmented Worms
EX; Earthworms, leeches & polychaetes Segments, true coelomates Most are hermaphroditic
Arthropods--- So many!!!!!!
MOST DIVERSE ANIMAL PHYLUM Segmented bodies Jointed Appendages Exoskeleton made of Chiton
Crustaceans
2 body parts EX: Crayfish, Crabs, Lobsters, Pillbugs & Shrimp
Arachnids
8 legs & pedipalps No antennae Compound eyes Spiders & Scorpions
Antennae 6 legs Diverse
-Insects-----
Echinoderms
Spiny Skin Water Vascular System Radial Symmetry EX: Seastars, Sea Cucumbers, Brittle Stars, Sand Dollars
Chondrichthes
Cartilage Fish Sharks & Rays
Bony Fish Puffer fish, carp, salmon
Osteichthyes
Amphibians
Lives on water & Land 3 Chamber heart Eggs must stay damp
Reptiles
Rough Skin Amniotic Egg Ex: Snakes, Lizards & Crocodiles
Birds
Warm Blooded Flight Feathers?
Marsupials
Pouches
Monotremes Duck-Billed Platypus & Spiny Ant Eater Egg-Laying Mammals
Placental Mammals •Carry young in utero
