Ch.10   photosynthesis (1) Ch.10 photosynthesis (1) Presentation Transcript

  • Photosynthesis
  • Organisms that make food through photosynthesis: Photoautotrophs
  • Photosynthesis happens in the Chloroplast
    • Parts of a Chloroplast
      • Thylakoid
      • Grana
        • Stack of Thylakoids
      • Stroma
        • Liquid inside Chloroplast
  • Photosynthesis Equation
  •  
  •  
  •  
  • Melvin Calvin
  • The electromagnetic spectrum
  • Why are leaves green?
  • Determining an absorption spectrum
  •  
  • Chlorophyll is a Pigment
    • Pigments
    • Give a substance color
    • Plant pigments
      • Chlorophyll a – blue-green
      • Chlorophyll b – yellow-green
      • Carotenoids – yellow/ orange
  • Electrons in chlorophyll are excited by light

  •  
  • Cyclic Electron Flow: ATP Only
  • ATP is made in the Thylakoid Membrane
  • Comparison of chemiosmosis in mitochondria and chloroplasts
  • The Calvin cycle
  • The Calvin cycle
  • The Calvin Cycle converts CO 2 into Sugar
