  1. Chlorophyll
  2. Mesophyll
  3. Granum (grana plural)
  4. Photosystems
  5. thylakoid
  1. a stacks of thylakoids
  2. b where chlorophyll is stored
    include antenna complex/reaction center
    2 types= photosystem II and photosystem I (in order in which they occur, named in order of discovery)
  3. c cells where chloroplasts are located, in the middle of the leaf, have 20 to 100 chloroplasts
  4. d 3rd membrane inside the stroma
    set of membranes with an internal space (lumen)
    arranged into stacks
    where chlorophyll and other pigments are stored
  5. e pigment in chloroplasts that trap light

5 Multiple Choice Questions

  1. bright green chlorophyll A
    absorbs reds and blues, reflects green and yellow
  2. packets of energy that travel in waves, one of these energizes one electron
  3. GOAL=convert light energy to chemical energy
    1. occurs in thylakoid membranes
    2. light energy causes chlorophyll to spit out high energy electrons
    3. Electrons are replaced from H20
    4. Produce ATP and NADPH (electron carrier)
  4. GOAL=convert to storable form of chemical energy
    1. independent of light
    2. conver inorganic forms of carbon (CO2) into organic form to create glucose
    3. Uses products of the Light-Dependent reactions to fix the carbon
  5. holes on the underside of a leaf where gas is released

5 True/False Questions

  1. CAM photosynthesisonly fix carbon at night
    dry, desert environment
    only opens the stomata at night, which converts to a temporary carbon storage molecule, which is then used in the calvin cycle
    ex. cactus, aloe plants, succulants


  2. Cyclic pathwayspigment in chloroplasts that trap light


  3. Fluorescecells where chloroplasts are located, in the middle of the leaf, have 20 to 100 chloroplasts


  4. Chemiosmosisprocess that produceds ATP (ATP synthesis)


  5. C4 photosynthesisC4 plants
    before calvin cycle, CO2 is fized into a 4 carbon molecule
    seasonally (long, dry season)
    ex. corn, sugarcane, crabgrass
