Exploring Taxonomy: Classification of Living Things
E N D
Presentation Transcript
is a branch of science that deals with the classifications of living things Taxonomy .
Carolus Linnaeus 1753 Father of Taxonomy
Three Interrelated Parts of Taxonomy • Classification Arrangement into groups • Nomenclature Assignment of Names • Identification Determining Identity
Five Kingdom System • Animalia • Plantae • Fungi • Protista • Prokaryote/Monera
Protista • Unicellular/ • multicellular • 2. Autotrophic (plant-like) • - Euglena • -seaweeds • Heterotrophic (animal-like/protozoans) • -Amoeba • - Paramecium,
Fungi • Absorptive Chemoheterotrophs • Unicellular(yeast) • multicellular (mushroom, mildews) • 3. Heterotroph • 4. Decomposers
Kingdom Animalia • Multicellular • Heterotrophs
Fish • They breathe with gills. • They are cold blooded. • Their skin is covered with scales and bony plates. • They lay eggs and have live births. • Examples of fish are gold fish, sharks and lamprey.
Fish • An unusual example would be a sea horse and an eel. • A non-example would be a dolphin, whale and starfish.
Amphibians • They breathe with lungs and gills. • They are cold blooded. • Their skin is smooth and moist. • Their birth of young are eggs. • The examples are frogs, toads, salamanders, newt, and mud puppies.
Amphibians • African clawed frog is a unusual example. • The lizard is a non-example.
Reptiles • They breathe with lungs. • They are cold-blooded. • Their bodies are covered with dry scales. • They lay eggs. • Black snakes, Bearded dragons, Turtles, Crocodiles, and Alligators are reptiles.
Reptiles • Geckos and Skinks are unusual reptiles. • Frogs and Toads are non examples.
Birds • Birds breathe with lungs. • They are warm-blooded. • They are covered with feathers. • They give birth to eggs. • Examples of birds would be a red bird, hawk, and chicken. • Some unusual birds are the ostrich, flamingo, and penguin.
Birds • Some non-examples are the bat and the dragonfly.
Mammals • Mammals breathe with lungs. • They are warm blooded. • They have hair/fur. • Most give birth to live young. • Some examples are platypus, kangaroo,koala, bears, lions, tigers, and people. • Some unusual examples bats, whales, and dolphins
Mammals • Non-examples are sharks and penguins.
1.Phylum Porifera (sponges) • asymmetrical • Body has canal and pores • sessile (attached to object, cannot move)
2. Phylum Coelenterata/Cnidaria (coelenterates/stinging celled) • Stinging cells and hollow bodies • tentacles that surround a mouth Examples: • Jellyfish • sea anemone • coral • hydras
3. Phylum Platyhelminthes (Flatworm) • flattened body • One body opening • Many are parasites, some are Free-Living • Can regenerate Examples: • Planaria, Tapeworm
4. Phylum Nemathelminthes/ Nematoda (Nematodes/roundworms) • Round bodies with pointed ends • Males & females are separate Examples: • Hookworm • Ascaris • Pin worm
5. Phylum Annelida (segmented worm/annelids) • Body divided into segments (with setae) • Most are hermaphrodites & free living • Examples Earthworms Ragworms Leeches
6. Phylum Mollusca (soft-bodied/mollusks) • Soft body usually protected by a shell • Body covered by mantle • Have muscular foot • Most have separate sexes • Examples:snails, slugs, clams, cuttlefish, chitons, tusk shells, oysters, octopus and squids
7. Phylum Echinodermata (spiny-skinned/echinoderms) • 5 part body • spines • Tube Feet (with Suctions) • Examples:starfish/sea star, sea urchin, sand dollar,cucumber
8. Phylum Arthropoda (joint-legged/arthropods) • Jointed appendages • Segmented bodies • Exoskeleton that sheds by molting • Head, thorax, abdomen are main parts • Some separate sexes, hermaphrodites, parthenogenesis • Examples:spider, • scorpion, caterpillar, • shrimp, lobster, crabs, bees, fly
