Slide 1:The Classification ofLiving Things
Slide 2:Common basis for communication about different
groups of living things.
Human attempt to make sense of the tremendous diversity of the living world.
Imply evolutionary relationships (= phylogeny). Classification (Taxonomy) &
Nomenclature (Naming) Reasons for Classification
Slide 3:Carl von Linne
Carolus Linnaeus
1707-1765
Liked Latin so much he
Changed his name to Latin. Classification
Slide 4:A species is identified by both its genus name and species name.Example: Zea mays (corn)
Zea = genus name (The first letter of the genus is always capitalized!)mays = species name Binomial Nomenclature Without a scientific name, if you asked for corn in Asia, they may translate it to beans!! Scientific names are very specific!!!
Slide 5:Classification
Slide 6:Example of Coral Classification The Mushroom CoralFungia scutaria Phylum Cnidaria Class Anthozoa Order Scleractinia Family Fungiidae Genus Fungia Species scutaria
Slide 7:Bears Ursus arctos Alaskan Brown Bear Ursus maritimus Polar Bear Ursus americanus American Black Bear
Lobsters Homarus americanus Atlantic Clawed Lobster Panulirus marginatus White-Margined Hawaiian Spiny Lobster Panulirus penicellatus Green Hawaiian Spiny Lobster
Cats
Felis domesticus House Cat Puma concolor Mountain Lion
Panthera leo Lion Examples of Scientific Names for Selected Species
Slide 8:Five Kingdoms of Life
Slide 9:Cell Structure Prokaryote versus Eukaryote Cell Wall Present or Absent Cell Wall Chemistry Presence or Absence of other OrganellesCellularity Unicellular versus Multicellular Level of Organization of Cells into Tissues Major Characterisitics Used to Classify
Organisms into Kingdoms
Slide 10:Prokaryotic, single-celled organisms.
Some with cell walls, but cell walls composed of peptidoglycan, not cellulose (as in higher plants).
Includes heterotrophic eubacteria, cyanobacteria, and archaeobacteria. Kingdom Monera
Slide 11:Kingdom Monera
Slide 12:Heterotrophic Eubacteria Kingdom Monera
Slide 13:Cyanobacteria Kingdom Monera
Slide 14:Eukaryotic, generally single-celled, organisms.
If multicellular, then cells are not well-organized into tissues and organs (more colonies of cells).
A very heterogeneous group include both heterotrophic and photoautotrophic forms.
Includes protozoa (e.g., Paramecium, Amoeba,) and algae (e.g., diatoms, dinoflagellates, Volvox, & most seaweed groups). Kingdom Protista
Slide 15:Amoeba Stentor Vorticella Paramecium Kingdom Protista: Protozoa/Animal-Like
Slide 16:Kingdom Protista: Algae/Plant-Like diatoms dinoflagellates volvox spirogyra
Slide 17:Kingdom Protista: Fungus-Like Water Molds Slime Molds Downy Mildews
Slide 18:Eukaryotic, generally multicellular, organisms (a few species, e.g., yeast are unicellular).
Heterotrophic, saprophytic (absorptive) nutrition.
Most with cell walls (usually composed of chitin) and complex life histories.
Includes molds, yeasts, rusts, and mushrooms. Kingdom Fungi
Slide 19:Kingdom Fungi
Slide 20:Eukaryotic, multicellular organisms with cells organized into distinct tissues.
Photoautotrophic nutrition.
Most adapted for a terrestrial existence and possessing vascular tissues.
Cells with chloroplasts and cellulose cell walls.
Includes mosses, ferns, pine trees, cycads, ginkgos, and flowering plants. Kingdom Plantae
Slide 21:Kingdom Plantae
Slide 22:Eukaryotic, multicellular organisms with cells organized into distinct tissues.
Heterotrophic, ingestive nutrition.
Most exhibit significant capacity for locomotion.
Cells not surrounded by cell walls.
Includes sponges, sea anemones, snails, insects, sea stars, fish, reptiles, birds, and human beings. Kingdom Animalia
Slide 23:Kingdom Animalia: Invertebrates
Slide 24:Kingdom Animalia: Vertebrates
