  1. 1.17 Energy Flow and Photosynthesis Pages 72-76

  2. Energy Sunlight is the source of energy for all living things. Image from kentkedl.com

  3. Step 1 Plants store energy as the carbohydrateglucose. Image from npic.orst.edu

  4. Step #2 The energy stored in glucose is transferred to ATP. Image from biotek.com

  5. Photosynthesis • Green plants Cyanobacteria Plantlike protists psychedelicporcupine.co.edu serc.blog.si weed-science-classes.wikispaces.com

  6. Cellular respiration • Occurs in all organisms (plants, animals, fungi, bacteria, protists) thesun.co.uk plus.google.com scraps20.com

  7. Autotroph • Producer • Makes its own food

  8. Heterotrophs • Organisms that rely on other organisms for energy. Startswithabang.com en.wikipedia.org saberchill.com

  9. Photosynthesis Chlorophyll, found in chloroplasts, absorbs light energy light energy + 6 CO2 + 6 H2O 6 O2 + C6H12O6

  10. Chloroplasts • Thylakoids-interconnected compartments • Grana- stacks of thylakoids • Stroma – fluid • Chlorophyll – green pigment

  11. Light Reactions • Trap energy from the sun and store it as ATP.

  12. Calvin cycle Carbohydrates from carbon dioxide

  13. Accessory Pigments • Orange carotenoids • Yellow xanthophylls • Red anthocyanin
