Presentation Transcript

  1. PHOTOSYNTHESIS

  2. Autotrophs • Identify the different types and give examples.

  3. Chloroplast • Describe the structure of the chloroplast. • Describe where most chloroplasts are located in a leaf. 

  4. Photosynthesis vs. Respiration • Compare and contrast the two processes. • Explain the role of redox reactions in photosynthesis

  5. Absorption Spectrum • Describe the relationship between an action spectrum and an absorption spectrum. • Explain why the absorption spectrum for chlorophyll differs from the action spectrum for photosynthesis. • List the wavelengths of light that are most effective for photosynthesis

  6. Plant Pigments • Explain what happens when chlorophyll or accessory pigments absorb photons.

  7. Photosystems • List the components of a photosystem and explain their functions.

  8. Photosystems • What are the outcomes of events in Photosystem II? • What happens in Photosystem I?

  10. Cyclic vs. Noncyclic • Compare cyclic and noncyclic electron flow and explain the relationship between these components of the light reactions. • Non-Cyclic • http://video.search.yahoo.com/video/play?p=cyclic+photophosphorylation&n=21&ei=utf-8&fr=yfp-t-701&fr2=tab-img&tnr=21&vid=0001667774425 • Cyclic http://video.search.yahoo.com/video/play?p=cyclic+photophosphorylation&n=21&ei=utf-8&fr=yfp-t-701&fr2=tab-img&tnr=21&vid=0001667774428

  11. Chemiosmosis • Compare/contrast photophosphorylation (chloroplast) to oxidative phosphorylation (mitochondria).

  12. Light vs. “Dark” • Make a chart of products and reactants for the light reactions and the Calvin Cycle. • What are Rubisco’s two claims to fame? • http://video.search.yahoo.com/video/play?p=Calvin+cycle&n=21&ei=utf-8&fr=yfp-t-701&fr2=tab-img&tnr=21&vid=000152530750

  13. Photorespiration • What happens to rubisco when the O2 concentration is much higher than CO2 • Describe the major consequences of photorespiration.

  14. Photosynthetic Adaptations • Name and describe two photosynthetic adaptations to counter photorespiration.

  15. Leaf Adaptations • Describe structural modifications in leaves adapted to avoid photorespiration.

  16. Where does it go? • What are the various fates of  glucose molecules made in photosynthesis? • http://video.search.yahoo.com/video/play?p=chloroplast&n=21&ei=utf-8&fr=yfp-t-701&fr2=tab-img&tnr=21&vid=0001675582539
