Transcript of "Photosynthesis2"

  1. 1. <ul><li>Based on what you discovered yesterday, why do leaves change colors in Autumn? </li></ul>
  2. 2. Photosynthesis
  3. 3. What is Photosynthesis? <ul><li>Process by which green plants convert the energy from sunlight or light into chemical energy (glucose). </li></ul><ul><li>Obtains the energy from white light. </li></ul>
  4. 4. Autotrophs vs. Heterotrophs <ul><li>Autotrophs---producers, makes their own food </li></ul><ul><li>Heterotrophs---consumers, must obtain or eat food </li></ul><ul><li>Autotrophs go through photosynthesis OR Chemosynthesis </li></ul>Autotrophs vs. Heterotrophs
  5. 5. Photosynthesis/Respiration Cycle
  6. 6. Ingredients of Photosynthesis <ul><li>White Light (Sunlight) </li></ul><ul><li>Pigments </li></ul><ul><ul><li>Chlorophyll </li></ul></ul><ul><ul><li>Accessory Pigments </li></ul></ul><ul><li>ATP </li></ul><ul><li>CO2 </li></ul><ul><li>H2O </li></ul>
  7. 7. ATP <ul><li>ATP = adenosine triphosphate </li></ul>Big Energy Bond – Lots Chemical Energy Released P P P Three phosphate groups Adenine nitrogen group Ribose sugar
  8. 8. ADP-ATP Cycle ADP P ATP
  9. 9. White Light <ul><li>White Light= ROY G BIV </li></ul><ul><li>Colors Appear the way they do because the light is REFLECTED </li></ul><ul><li>WHAT LIGHT IS IMPORTANT IN PHOTOSYNTHESIS?... </li></ul>
  10. 10. Types of Pigments <ul><li>Chlorophyll---Green (reflected) </li></ul><ul><li>Accessory Pigments </li></ul><ul><ul><li>Carotenoids: </li></ul></ul><ul><ul><ul><li>Xanthophyll---Yellow </li></ul></ul></ul><ul><ul><ul><li>Carotene---Orange </li></ul></ul></ul>
  11. 11. Why so many colors?
  12. 12. Formula for Photosynthesis <ul><li>H 2 O + CO 2 O 2 + C 6 H 12 O 6 </li></ul>
  13. 13. Where Photosynthesis Takes Place <ul><li>Leaf </li></ul><ul><li>Mesophyll Cells </li></ul><ul><li>Organelle responsible for Photosynthesis </li></ul><ul><ul><li>Chloroplast </li></ul></ul><ul><ul><ul><li>Contain Plant Pigments That Capture the Sun’s Energy </li></ul></ul></ul><ul><ul><ul><li>Thylakoid- Light Reactions </li></ul></ul></ul><ul><ul><ul><li>Stroma- Dark Reactions </li></ul></ul></ul>
  14. 14. Where the 2 Reactions of Photosynthesis take place                                   
  15. 15. Thylakoids <ul><li>This is where the first phase of Photosynthesis takes place. </li></ul><ul><li>Which is also know as the light reaction . </li></ul><ul><li>Involves the trapping of light energy and the formation of materials. </li></ul><ul><li>Produces Oxygen by breaking down H 2 O into free Electrons, H + and O </li></ul><ul><li>H+ go to stroma, releasing energy for ATP Production. </li></ul>
  16. 16. Stroma <ul><li>This is where the second phase, the Calvin Cycle, of Photosynthesis takes place. </li></ul><ul><li>Which is also known as the dark reaction . </li></ul><ul><li>Produces glucose from H + and CO 2 . </li></ul><ul><li>Uses the products from the light reactions to form glucose. </li></ul>
  17. 17. Summary! <ul><li>Green Plants Are Excellent At Capturing the Sun’s Energy </li></ul><ul><li>They Make A Huge Amount of Glucose With A Little Of Energy From the Sun </li></ul><ul><li>Hey, They Actually Eat Their Own Glucose Through Aerobic Respiration </li></ul>
