Bio1151 Chapter 10 Photosynthesis
  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              pigment molecules.







     
     
     
     
  5. There are two major stages: the        reactions and the         cycle (light-independent reactions).

     
     
     
     
    • The light reactions occur in the            , where chlorophyll pigments absorb light and excite some electrons.

       
       
       
       
    • Each excited electron is passed through two               where the energy is used to produce      and        .



       
       
       
       
    • 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.
