Presentation Transcript

  1. 10-15 minutes Warm Up 11/13 & 11/14/12 • Copy objective: I will be able to investigate and explain cellular processes like energy conversions, and synthesis of new molecules. Answer: • 1. Identify the four biomolecules and their functions. • 2. Explain how the cell membrane maintains homeostasis in the cell. • 3. Write two things you know about photosynthesis.

  2. 5 minutes Needs to be turned into the box by end of day today • From Last Class • MOY I • From Today • SCA 3 Post Test • Cell Energy Reading • Exit Ticket • Cans/ Coats for Can/Coat Drive

  3. 25 minutes Prep for SCA 3 Post Test and Test • Read each question and answer carefully • Yes this is for a grade • Double Check your answers when done • When you are done raise your hand and I will pick it up and get you started on the preview for the next unit

  4. 10 minutes Preview for Cell Energy Unit • Read the selection about Photosynthesis and cell energy • Number the paragraphs (1, 2,3,4…) • Underline or Highlight words that you feel are important or you don’t understand • Write a one sentence summary of each paragraph

  5. 10 minutes Learning Adventure • We are going outside • You mission • To find 1 green leaf and 1 brown leaf • When we return • Compare and contrast the leaves

  6. 15 minutes Photosynthesis Notes

  7. Hetero vs Auto • Review • Autotrophsuse sunlight to create food • Heterotrophs get energy from either autotrophs or other heterotrophs

  8. Glucose • Carbohydrate formed during photosynthesis • Made of oxygen, hydrogen, and carbon • Chemical formula • C6H12O6

  9. Chloroplasts • Photosynthesis takes place in the chloroplast of the plant

  10. Chlorophyll • Makes plant appear green • Traps sunlight

  11. Photosynthesis • Photosynthesis includes two main groups of reactions: 1. light reactions 2. Calvin cycle

  12. Where does the light go? • Light reactions • Water molecules are split • Produces • Hydrogen Ions • ATP and NADPH (energy sources used in Calvin Cycle) • Oxygen (released by plant)

  13. Calvin Cycle • Takes place in stroma • Energy from light reactions, carbon dioxide and hydrogen ions combine: • Glucose formed Glucose

  14. Photosynthesis Reactants Products

  15. In the End • The complete equation for photosynthesis in the end Is this balanced?

  16. The Balanced Equation

  17. 5 minutes Notes Summary • Please write a 4-5 sentence summary of the notes we just took • Focus on the main points

  18. 10 minutes Exit Ticket Questions • Where does photosynthesis take place in the plant cell? • What is the simple sugar formed during photosynthesis? • How many oxygen molecules does it take to make one glucose molecule? • What are the two cycles of photosynthesis?
