Science 7 notes glb lab 06 green factories

  1. 1. Green FactoriesObserving Structures of Producers
  2. 2. Key Objectives:Key Objectives:The student will:– Investigate and understandcell structure and organelles– Describe cell organelles andtheir functions
  3. 3. Key Objectives:Key Objectives:The student will:– Investigate and understandthe basic needs and lifeprocesses of plants– Identify how plants obtain theresources they need tosurvive
  4. 4. Key Objectives:Key Objectives:The student will:– Investigate and understandthe physical and chemicalprocess of photosynthesis
  5. 5. Key Objectives:Key Objectives:The student will:– Investigate and understandthe physical and chemicalprocess of cellular respirationand its importance to plant life
  6. 6. Key Objectives:Key Objectives:The student will:– Investigate and understandthat photosynthesis is thefoundation of virtually all foodwebs
  7. 7. Key Objectives:Key Objectives:The student will:– Relate the role of producer tothat of consumers in a foodchain or food web
  8. 8. Key TermsKey TermsPhotosynthesisStoma (stomata )Guard CellsReactantProductChemical Bond
  9. 9. PhotosynthesisThe life process carried out inchloroplasts within some plantcells:– Energy from light is used tomake food molecules(Glucose - C6H12O6)
  10. 10. Photosynthesis
  11. 11. Photosynthesis
  12. 12. Stoma (stomata-plural)Openings in the undersideepidermis of a green leaf thatallow for Carbon Dioxide (CO2),Oxygen(O2) and water vapor toenter and exit the leaf
  13. 13. Stoma (stomata)
  14. 14. Guard Cell(s)Two small leaf cells on eachside of the stoma that open andclose the stoma
  15. 15. Guard Cell(s)STOMAOPENSTOMAGUARD CELLS
  16. 16. ReactantIn a chemical equation theseare the chemicals that beginthe process or what goes in tothe equation6 CO2 + 6 H2O  C6H12O6 + 6 O2
  17. 17. ProductIn a chemical equation theseare the chemicals that end theprocess or what comes out ofthe equation6 CO2 + 6 H2O  C6H12O6 + 6 O2
  18. 18. Chemical BondThe result of a chemicalreaction when two reactantscombine chemically to formnew products
  19. 19. Lab TimeLab TimeNow it is time to introducethe new lab.Pease open your Green labguides to page 65Read the introductionsilently as I read it aloud
  20. 20. Slides for lab activityWhat do Plants need forPhotosynthesis?– Sunlight– Chlorophyll– Water H2O– Carbon Dioxide CO2
  21. 21. Slides for lab activityHow do you think plants get thethings for photosynthesis?– Chloroplasts in LeavesAbsorbs sun light– RootsWater in– StomaCO2 in, O2 out through the underside of theleaf. Water Vapor out
  22. 22. Aquatic Producers
  23. 23. Elodea Magnified
  24. 24. Elodea Cells Magnified X1000CHLOROPLASTSCELL WALLSCYTOPLASMNUCLEUS
  25. 25. Tradescantia
  26. 26. Tradescantia leaf Magnified X100STOMAGUARDCELLSSTOMATANUCLEUSCELLwALL
  27. 27. Stoma and Guard CellsSTOMA GUARDCELLS
  28. 28. PrivEt leaf Magnified X100PALISADE LAYERVASCULAR BUNDLES (VEINS)SPONGEY LAYER
  29. 29. Privt leaf Magnified X1000Mesophyll Cells(Tighten Vascularcells)
  30. 30. Photosynthesis
  31. 31. Essential LearningsOrganisms that performphotosynthesis are calledproducers because they makeor produce their own food.Consumers and Decomposersmake up everything else
  32. 32. Essential LearningsPhotosynthesis isthe process inwhich producersmake food byusing lightenergy, carbondioxide and water
  33. 33. Essential LearningsChlorophyll is a green coloredchemical inside chloroplasts thatallows for the process ofphotosynthesis to take placeChloroplasts must be present inthe producer to performphotosynthesis
  34. 34. Essential LearningsCarbon dioxide (CO2) and water(H2O) are the raw materialswhich plants must obtain fromthe environment forphotosynthesis
  35. 35. Essential LearningsTo obtain materials needed forphotosynthesis, plants have rootsand stems to absorb water, leavescontaining chloroplasts to collectlight and stomata on the undersideof each leaf to allow for theexchange of gases
  36. 36. Essential LearningsThe stomata located on theunderside of the leaf’s epidermis iscontrolled by guard cells whichopen and close each stoma toallow for the exchange of carbondioxide (in) and oxygen and watervapor (out)
  37. 37. Essential LearningsPlants produce sugar calledglucose for food and oxygen asbi-product duringphotosynthesis
  38. 38. Essential LearningsFirst level/primary Consumerscalled Herbivores eat the plantsto get energy from the glucosestored inside the plant.– Ex. Insect
  39. 39. Essential LearningsSecondary consumers calledCarnivores eat the Herbivores– FishThird-level or Tertiary consumerscalled Omnivores eat everything toget their energy– Bear
  40. 40. Essential LearningsDecomposers break down thewaste products and deadorganisms and return thenutrients to the soil
