1. PHOTOSYNTHESIS

2. ENERGY AND LIFE Autotrophs  Use sunlight to create food molecules which are broken down for cellular energy.  PLANTS Heterotrophs  Consume food molecules (other cells) which are then broken down for cellular energy.  Not Plants

3. ENERGY MOLECULES  ATP: adenosine triphosphate  ADP: adenosine diphosphate  NADPH: another high energy molecule.  NADP+: the counter part to NADPH

4. PHOTOSYNTHESIS  Photosynthesis occurs in the chloroplast.  Photosynthesis is the process of creating food molecules from sunlight energy. 6CO 2 + 6H 2 O + sunlightC 6 H 12 O 6 + 6O 2

5. HOW IS SUNLIGHT “COLLECTED”?  Chlorophyll: a pigment (colored molecule) that absorbs the different colors of light, except for green light.  Absorbing light means absorbing energy because light=energy.

6. CHLOROPLASTS AND CHLOROPHYLL…  Chlorophyll is contained inside the chloroplasts.  Photosynthesis reactions take place in the chloroplasts.

7. CHLOROPLAST Where photosynthesis “light dependent” reactions take place. Where photosynthesis “dark” reactions (AKA the Calvin Cycle) take place.
