Transcript

  • 1. CLASSIFICATION with Holt and UnitedStreaming
  • 2. Classification
    • Classification is: the grouping of organisms by similar characteristics
    • Taxonomy: the science of classification
    • We use a Dichotomous Key which consists of several pairs of descriptive statements where only one will apply to the unknown organism
  • 3. Who did it and how?
    • Carl Linnaeus (1700): this scientist classified things by form and structure
    • He gave organisms a genus and species name (binomial nomenclature)
  • 4.
    • Latin : the language commonly used for classification
    • Because it does not change and can be used worldwide
  • 5. What order is that?
  • 6.  
  • 7. Binomial Nomenclature examined
    • Species: a group of organisms that can produce viable offspring (viable means it can have its own offspring)
    • Genus: a group of different species that are similar
    • Felis catus ( household cat )
  • 8. Binomial Nomenclature
  • 9. Six kingdoms
    • Two prokaryotic kingdoms:
      • Archaebacteria
      • Eubacteria
    • Four Eukaryotic kingdoms:
      • Protist
      • Plantae
      • Fungi
      • Animalia
  • 10. Kingdoms, in depth
  • 11.
      • Both are Unicellular with No Nucleus ( Prokaryotes )
      • Archaebacteria can live where most organisms could not survive (deep ocean vents, hot spring)
      • Eubacteria make up most of the other kinds of bacteria on earth.
    • Example: E. coli, Hot springs algae
    Archeabacteria & Eubateria
  • 12. Protists
    • Unicellular (one celled) and multi-cellular eukaryotic
    • have a nucleus
    • autotrophs and heterotrophs
    • Example: euglena, paramecium, slime molds
  • 13.  
  • 14. Fungi
    • unicellular and multicellular
    • Heterotroph (obtains energy from other source)
    • Example: mushrooms, yeasts, molds
  • 15.  
  • 16. Animals
    • multicellular but no cell wall
    • heterotrophs - does not make own food
    • have tissues, organs, organ systems
    • Most move
  • 17. Plants
    • multicellular or unicellular eukaryotic with a cell wall
    • have a nucleus
    • autotrophs- makes own food ( photosynthesis )
    • Example: sequoia, flowers
  • 18. Do you know plants? The Plant Kingdom: A quick overview
  • 19. Plants
    • Plants are multicellular
    • Plants make their own food ( autotrophs )
    • There are lots of examples!
  • 20. 2 main groups
    • Plants are either vascular or nonvascular
    • Vascular tissue is like tubes that carry water through the plant
  • 21. Nonvascular plants
    • Have no pipes to transport water
    • They rely on diffusion and osmosis
    • Have no true stems, roots or leaves
    • They are small
  • 22. nonvascular
    • Examples are mosses and liverworts
                                   
  • 23. Vascular plants
    • Have tissues or pipes to transport water
    • Have stems, roots and leaves
  • 24. 2 categories
    • There are 2 types of vascular plants, those that have seeds and those that have no seeds
  • 25. Seedless vascular plants
    • Examples are ferns, club mosses and horsetails.
                                                         
  • 26. Vascular plant with seeds
    • The vascular plants with seeds are divided into 2 categories:
    • Nonflowering
    • Flowering
  • 27. Nonflowering seeded plants
    • Called gymnosperms
    • Examples are conifers (trees that produce cones) and ginko trees
                                         
  • 28. Flowering seeded plants
    • Called angiosperms
    • Examples are corn, tulips, water lillies, peach trees, magnolia trees, grass, palm trees, cactus, cotton plants and much more!
  • 29. Angiosperms
  • 30. How can I learn more?
    • More information on all of these plants can be found in your book in Chapter 12, pages 270-283.
    • Now, let’s see what you remember…
  • 31. What are the 2 main groups of plants?
  • 32. Answer: Vascular and Nonvascular Which of these two groups includes plants that are large and have pipes to carry water?
  • 33. Answer: Vascular Is a moss vascular or nonvascular?
  • 34. Answer: Mosses are nonvascular What are the 2 main groups of vascular plants?
  • 35. Answer: gymnosperms and angiosperms Are pine trees gymnosperms or angiosperms? G: nonflowering A: flowering
  • 36. Answer: Pine trees are gymnosperms . Which one is not an angiosperm? Water lily Tomato plant Cactus Fern Palm tree Corn Tulip
  • 37. Answer: Only the fern is seedless and nonflowering .
  • 38. Plants: We can’t survive without them! 6 correct: you’re an expert! 4-5: You are knowledgeable about plants. 3: You are learning… 1-2: Study up! 0: Shame on you!
