  1. LIFE All living things: 1. Are composed of cells 2. require energy 3. reproduce 4. display heredity – pass traits down from parent to offspring 5. respond to the environment 6. maintain homeostasis – keep within normal range 7. evolve and adapt

  2. LIFE DEFINITIONS • II. Some Definitions of Life: • Life: The property manifested in functions such as metabolism, growth, response to stimulation, and reproduction, by which living organisms are distinguished from dead organisms or from inanimate matter. (Webster's Dictionary) • Life: The state of being which begins with generation, birth, or germination, and ends with death; also, the time during which this state continues; that state of an animal or plant in which all or any of its organs are capable of performing all or any of their functions; used of all animal and vegetable organisms. (Gray's Medical Dictionary)

  3. Classification - 6 Kingdoms • Archaeans • Monerans • Protists • Fungi • Plants • Animals

  4. Archaeans • 1 cell • No true nucleus • Live in extreme environments • High temperatures • High salinity • High methane concentrations

  5. KINGDOM MONERA (monerans) *1 cell *no true nucleus - prokaryote –*examples - bacteria, blue-green bacteria (cyanobacteria)

  6. KINGDOM PROTISTA (protists) *1 cell *have a true nucleus – eukaryote *examples - amoeba, diatom, euglena, paramecium, some algae (unicellular), etc

  7. KINGDOM FUNGI *multicellular *have nuclei*mainly do not move from place to place*heterotrophic – must get food (food is digested outside of fungus)*examples - mushroom, mold, puffball, shelf/bracket fungus, yeast, etc

  8. KINGDOM PLANTAE (plants) *multicellular *have nuclei *do not move *autotrophic – makes own food *examples - multicellular algae, mosses, ferns, flowering plants (dandelions, roses, etc.), trees, etc

  9. KINGDOM ANIMALIA (animals) *multicellular *have nuclei *do move *heterotrophic – must get food *examples - sponge, jellyfish, insect, fish, frog, bird, lion, humans

  10. Classification • Kingdom – King • Phyllum – Philip • Class - came • Order – over • Family – for • Genus – good • Species – sphaghetti

  11. Classification of living things • Kingdom - Animalia • Phylum - Chordata • Class - Mammalia • Order - Carnivora • Family - Felicidae • Genus - Panthera • Species – Leo • LION – Panthera Leo

  12. Classification of Humans • Kingdom:   Animalia Phylum:   Chordata (Subphylum:   Vertebrata)Class:   MammaliaOrder:   Primates  Family:   HominidaeGenus:   HomoSpecies:   sapiens Humans – Homo sapiens

  13. BINOMIAL NOMENCLATURE • Scientific names - 2 name naming system • The genus and species name are used to name each species • Ex. Lion is Panthera Leo • Ex. Humans are Homo sapiens
