Unit 2: The Cell Photosynthesis Review
  1. Plants and other are the of ecosystems.
     
     
     
     
  2. Photoautotrophs can convert solar energy into the energy in food by a process called .
     
     
     
     
  3. Photosynthesis is a process where water is and carbon dioxide is to .
     
     
     
     
  4. In plants, photosynthesis occurs in organelles called chloroplasts, which contain its own pigment molecules.
     
     
     
     
  5. There are two major stages: the reactions and the cycle (light-independent reactions).
     
     
     
     
    • The light reactions occur in the , where pigment molecules located in a photosystem absorb light and their electrons reach an state.
       
       
       
       
    • Each excited electron is passed through an transport chain (ETC) and another photosystem, where the energy is used to produce and reduce NADP+ to .
       
       
       
       
    • The Calvin cycle occurs in the to synthesize from carbon dioxide.
     
     
     
     
  6. plants are adapted to hot, dry climates by incorporating CO2 into -carbon as the substrate in the Calvin cycle.
     
     
     
     
  7. The production of carbon compounds from CO2 is called fixation.
