  1. Chloroplast
    the cellular organelle where photosynthesis takes place
  2. Chlorophyll
    gives organelles a green color
  3. Stomata (stoma - s)
    tiny pores found on the surface of a leaf
  4. Stroma
    a thick fluid enclosed by the inner membrane of the chloroplast
  5. Thylakoid
    • disk-shaped sac in the stroma of a chloroplast
    • site of the light reactions of photosynthesis
    • arranged in stacks called grana (granum - s)
  6. Chemical Equation for Photosynthesis
    • CO2 + H2O ---C6H12O6 + O2
    • carbon dioxide + water --- glucose + oxygen
  7. Light Reactions
    • the chemical reactions convert the sun's energy to chemical energy
    • takes place in the membranes of thylakoids in the chloroplast
    • oxygen is a waste product
    • produce ATP and NADPH
  8. Calvin Cycle
    • cycle in plants that makes sugar from carbon dioxide, H+ ions, and high-energy electrons carried by NADPH
    • does not directly require light to begin
    • uses ATP and NADPH to convert carbon dioxide to sugar
  9. Wavelength
    the distance between to adjacent waves
  10. Electromagnetic Spectrum
    range of types of electromagnetic energy from gamma waves to radio waves
  11. Pigment
    chemical compound that determines a substance's color
  12. Paper Chromatography
    laboratory technique used to observe the different pigments in a material
  13. Photosystem
    cluster of chlorophyll and other molecules in a thylakoid
  14. RuBP
    • a material regenerated in Calvin cycle
    • a sugar with five carbons
  15. Carbon Cycle
    the process by which carbon moves from inorganic to organic compounds and back
  16. Greenhouse Effect
    process by which atmospheric gases trap heat close to Earth's surface and prevent it from escaping into space
