  1. 10/30 & 10/31 - 7th Grade Agenda Learning Objective: Learn about Respiration Collect HW: Reading & Note Taking p.71 – 73 Chap 3 Test Video: Science in Action Photosynthesis Class Reading: 124 - 127 HW: Reading & Note Taking p.74 & 75 Reminder: HW: Cell Model due 11/4 & 11/5 (40 Points)

  2. Reflection • Prompt: What is respiration. What is the difference between photosynthesis and respiration? (Write in complete sentence)?

  3. Chap 4 Photosynthesis • What is Photosynthesis?

  4. Photosynthesis • Photosynthesis: The process by which a cell captures the e________ in sunlight and uses it to make f______. nergy ood

  5. Photosynthesis: 2 Stage Process • Stage 1:Capture Sunlight (energy) through Chloroplasts • Stage 2: Use captured water, energy and carbon dioxide to produce sugar and oxygen

  6. Chloroplasts orophyll • Chl________ pigments inside chloroplasts absorb su________ and convert it into energy nlight Chloroplasts

  7. Stomata arbon • C_________ D________ is absorbed through openings in the underside of the leaves called Stomata ioxide

  8. Close up of Stomata

  9. Do plants produce carbon dioxide? (Yes or No) • Can plants produce oxygen at night? • How can plants create the required energy at night? At night, plants breath in small amount of oxygen and produce carbon dioxide

  10. Autotrophs & Heterotrophs • Which organisms in these photos are autotrophs? • Which organisms in these photos are heterotrophs?

  11. What is Respiration? • What is respiration?

  12. Respiration Demonstartion • Cup your hand and hold it over your mouth • Breath out • Rub your hands

  13. What is Respiration? tosynthesis • During pho______________ plants capture and save en_____ in the form of car_________ (sugars and starches) ergy bohydrate

  14. What is Respiration? • After you e__, your body converts the carbohydrates into gl_______ (type of sugar) at ucose

  15. Respiration: 2 Stage Process ucose • Stage 1: Gl______ is broken down into smaller molecules • Stage 2: Mit________ takes the ox______ and glucose and converts it into ca_____ dioxide, w______ & energy ochondria ygen rbon ater

  16. What is the relationship between Photosynthesis and Respiration? • Photosynthesis and respiration can be thought of as opposite processes • Together these two process form a cycle that keeps the level of oxygen and carbon dioxide fairly constant

  17. Fermentation provides en_______ from cells without using ox_______ ergy ygen

  18. Alcoholic Fermentation: Y_____is used to break down s______ and produce carbon dioxide (making br_____ and be_____) east ugar ead er

  19. Lactic Acid Fermentation happens when you over work your m_______ and your cells don’t get enough o_______ uscle xygen
