1. Learning Target 12.Compare & contrast the structure & function of mitochondria & chloroplast 15. Determine what factors affect the process of photosynthesis & cellular respiration

2. Location, location, location Where does the Light Dependent Reaction occur? The Light Independent reaction?

3. Chloroplast Structure Found in mesophyll 1 mesophyll cell may have 30 chloroplasts Stomata regulate passage of CO 2, O 2 and H 2 O

4. Learning Check Where does the Light Dependent Reaction occur? The Light Independent reaction? What factors could affect the process of photosynthesis?

5. Learning Targets 11. Describe the purpose of Chlorophyll & Accessory pigments.

6. Pigments Absorb light energy Boost e -  become unstable! Chlorophyll Chlorophyll a  main pigment  blue-green Chlorophyll b  accessory pigment  yellow-green Other accessory pigments  absorb different wavelengths of light Carotenoids  yellow-orange Xanthophyll  yellow Rhodophyll  red Fucoxanthin  brown Why are plants green? Why are plants changing color?

7. Photosystems Pass energy  reaction center (chlorophyll a molecule)  transfers energy to primary electron acceptor antenna pigments are primarily chlorophyll b, carotenoids & xanthophyll

8. Learning Check What is the purpose/function of pigments?
