  1. What does the word “producer” mean? • Describe what comes to mind when you hear the word producer. • Give some examples of producers. Journal Week: 10, Monday, October 29th

  2. Relate producers to photosynthesis • Describe the process of photosynthesis Objectives:

  3. Photosynthesis:a process that captures energy from the sunlight to make sugars that store chemical energy Miss Hanna Biology I

  4. 6CO2 + 6H2O + Energy (Sunlight)6O2 +C6H12O6 • Carbon dioxide + Water + Energy Oxygen + Glucose 1) Formula

  5. To capture energy • Sunlight ATP • Make glucose (sugar) 2) Purpose

  6. Plants only • Organelle: Chloroplast • Structures Inside a Chloroplast (write under notes) • Thylakoids: saclike photosynthetic membranes in chloroplast • Grana (granum): stacks of thylakoids • Stroma- region outside thylakoid membrane • Chlorophyll: a molecule that absorbs some of the energy in visible light DRAW & LABEL THIS! 3) Location

  7. 2 Cycles in Photosynthesis • 4a) Light Dependent Reaction • Produces ATP • 4b) Light Independent -Calvin Cycle • Uses ATP from Light Reaction • Creates Sugar from Carbon dioxide 4) Cycles of Photosynthesis

  8. Location: Takes place in grana/thylakoid • Reactants: H20 and energy from light • Products: oxygen gas • Goal: convert ADP and NADP into the energy carriers ATP and NADPH (carries electrons for energy) for light independent reactions 4a) Light-Dependent Reactions

  9. No light required • Location: Stroma • Reactants: • ATP and NADPH created in the light dependent reactions • Uses CO2 • Products: high energy sugars (glucose 4b) Light-Independent Reactions  “Calvin Cycle”

  10. Draw this picture in your notebook  Light vs. Calvin

  11. Calvin Cycle

  12. Amount of water in the environment • shortage can slow/stop photosynthesis 5) Factors Affecting Photosynthesis

  13. Temperature • Between 0-35C degrees is ideal 5) Factors Affecting Photosynthesis

  14. Light intensity • Increase light will increase in photosynthesis until max rate is reached 5) Factors Affecting Photosynthesis

  15. -On a half sheet of paper…answer these. • What is Required for Light Dependent Reactions? (Reactants) • What is Produced in Light Dependent Reactions? • What is Required for Light Independent Reactions? (Reactants) • What is Produced in Light Independent Reactions? Ticket out the Door: Photosynthesis Review
