  1. FQ: What do plants need to grow? • Entry Task: make a list of what you know plants need in order to grow. Also list any questions that come to mind about this same questions.

  2. Lets make a class list: • Sunlight • Water • Co2

  3. Focus Questions • How does a plant use sunlight to grow? • How does a plant use water to grow? • How does a plant use CO2 to grow? Investigative Questions • How does sunlight affect plant growth? • How does amount of water affect plant growth? • How does CO2 affect plant growth?

  4. How is your group going to do this investigation? • Procedure writing planner • What are your variables? • Do you have 3 conditions for your MV? • Do you have a controlled condition/control group? • Do you have at least 3 CV? • Did you specifically say to record the RV? • Did you include multiple trials?

  5. Photosynthesis Photosynthesis, CO2 and Plants The Energy of life (ATP) Structure of chloroplast + Photosynthesis overview

  6. Ch. 8 Vocabulary • Adenosine triphosphate • Heterotroph • Autotroph • Photosynthesis • Pigment • Chlorophyll • Chloroplast • Thylakoid • Stroma • NADP+ • Light dependent reaction • Light independent reaction

  7. Photosynthesis 8.1 • LT: Today I will… • Use a model to explain how ATP releases energy for the cell to use • Identify the pathways that cells use to make ATP • ET: What do the three letters in ATP stand for?

  8. ATP – Adenosine triphosphate • ATP is the cells source for quick energy • It powers all cell functions such as building proteins and opening ion channels for active transport Q: How does it work?

  9. Where do we get all the ATP our cells need? • What do we need in our bodies to to make ATP? • Stored glucose and fat • 3 processes that make ATP: • Cellular/Aerobic respiration:36 ATP • Lactic acid fermentation: 2 ATP • Alcohol fermentation: 2ATP

  10. How is this connected to Photosynthesis? • We need oxygen and glucose for cellular respiration

  11. Inside The Chloroplast

  12. Electrons? Carrier Molecules? • NADP+ = Nicotinamide adenine dinucleotide phosphate • We call it a “carrier” because like ATP, it traps a high energy electron in it’s bonds and takes where it needs to go in the chloroplast

  13. Electrons? From where?

  14. Photosynthesis Overview Light Independent • Basically

  15. Photosynthesis • The location • The Equation – Reactants and Products • The Importance

  16. FQ: What do plants need to grow? Lets revisit these questions from the start of the lab • How does a plant use sunlight to grow? • How does a plant use water to grow? • How does a plant use CO2 to grow?

  17. Data Collection and Discussion • Now it is time to check our plants and collect our data from the investigation. • Once you have your data collected DO NOT WRITE YOUR CONCLUSION • Discuss with your group the analysis question in the lab

  18. Analysis: Does our results from the lab support our current thoughts on what plants need to grow? Why or Why not? • With your group discuss your answers to this question • Compile your response into one statement on the whiteboard

  19. FQ: How does photosynthesis convert light energy into stored chemical energy in glucose?Time to apply what we know! • What is the recipe/steps to this process?

  20. Theatrical Depiction or Song lyrics • You group with be assigned one of the 2 types of models to illustrate the steps needed to convert light energy to chemical energy in photosynthesis. Your group will need to work through the following: • Organizing what you already know/ resources • Creating a storyline of steps • Converting those steps into the selected model

  21. Biology • Use a model to illustrate how photosynthesis transforms light energy into stored chemical energy (glucose) FQ’s: • What are the inputs and outputs of photosynthesis? • What are the 2 main processes in photosynthesis? • How can we break these 2 processes into steps for our model?

  22. Exit Ticket • What are the inputs and outputs of photosynthesis? • What are the 2 main processes in photosynthesis? • How has creating your model helped you learn the above 2?

  23. Biology – Getting read for the test • Mass of a plant worksheet/handout – Extra credit • Finish skits and songs • Work on study guide

  24. Cellular Respiration • Agenda: • New Seats • Tests Back • Pretest for CR • ET: Create the vocabulary list: • Cellular respiration • Aerobic • Anaerobic • Glycolysis • NAD+ • Krebs cycle • Alcoholic fermentation • Lactic Acid fermentation

  25. FQ: How is burning a marshmallow similar to our cells burning energy? • Make some generalizations in your notebook

  26. Use an entire page in your notebook to make this table.

  27. What is cellular respiration? • When your cells use glucose and oxygen to make ATP energy

  28. 1st - Glycolysis • Glycolysis: The splitting of glucose happens in the cytoplasm of the cell • Result: 2 pyruvic acid or pyruvate molecules

  29. if Oxygen is not available… • 2nd - Fermentation: 2 types • Lactic acid: 2 ATP’s, makes you sore • Alcohol: 2 ATP’s, makes alcohol

  30. If Oxygen is available…2nd – The Kreb cycle (citric acid cycle)3rd – Electron Transport Chain (ETC)

  31. Cellular Respiration and Exercise • LT: Today I will… • Make a prediction about how exercise affects cellular respiration • Test my prediction • ET: Review glycolysis, fermentation, and cellular respiration.

  32. FQ: Do plants use O2 to covert sugar into energy and release CO2 as a waste product as animals do?
