3. THE BIG PICTURE These experiments led to work by later scientists who finally discovered that in the presence of light, plants transform CO 2 and water into carbohydrates and release oxygen. _____________ + ____________ _______________ + ____________ Carbon dioxide WATERSugars Oxygen 6 CO 2 _____________ + ____________ _______________ + ____________ 6 H 2 OC 6 H 12 O 6 6 O 2 →

4. In addition to water and carbon dioxide, __________________ and __________________ are needed for photosynthesis to happen. chlorophyll light energy http://fig.cox.miami.edu/~cmallery/255/255phts/255phts.htm

5. ____________________ involves a complex series of chemical reactions, in which the product of one reaction is _____________ by the next reaction. Photosynthesis consumed Reaction 1 → Product → X Reaction 2 → Product Y A series of reactions linked in this way is referred to as a __________________________ biochemical pathway

6. PHOTOSYNTHESIS Light-Dependent Reaction Light-Independent Reactions Light & Water oxygen ATP NADPH Carbon Dioxide (CH 2 O) n Calvin Cycle

7. Visible light is made up of many different _______________of light Your eyes “see” different sizes of waves as different ___________ http://www.simontucket.com/_Portfolio/PortLarge/L_Il_Prism.jpg wavelengths colors

8. Plants gather the sun’s energy with light absorbing molecules called Pigments. By: VanderWal

9. The main energy absorbing molecule in green plants is ___________________ _________________ are plant pigments too. (These look yellow, orange, and red) CAROTENOIDS http://www.russianflora.com/store/images/product/custom_green_plant_35.jpg http://www.rnzih.org.nz/images/gardenimages/carrots_d.jpg CHLOROPHYLL

10. In ______, chlorophyll production slows as the trees shut down and photosynthesis stops for winter. FALL http://sps.k12.ar.us/massengale/ecology_notes_bi.htm
