  1. Photosynthesis vs. Respiration By: Brianna Shields October 19, 2004

  2. DO NOW • 1. Which type of cellular transport process moves food particles from areas of high concentration to low concentration? • 2. Which type of asexual reproduction is one in which a bacterium splits down the middle to form 2 identical cells? • 3. What is regeneration?

  3. GOAL • To understand the processes of photosynthesis and respiration with regard to energy flow in the ecosystem • To be able to draw and label a diagram of the carbon dioxide-oxygen cycle

  4. List atleast 3 things that this organism needs to live REVIEW

  5. Give 3 reasons as to how you know that this is a living organism REVIEW

  6. Explain how to calculate total magnification REVIEW

  7. What cell organelle is this? What does it do? Is it found in plant cells, animal cells or both? REVIEW

  8. What cell organelle is this? What does it do? Is it found in plant cells animal cells or both? REVIEW

  9. What cell organelle is this? What does it do? Is it found in plant cells, animal cells or both? REVIEW

  10. List atleast 2 organelles that are found only in this type cell REVIEW

  11. What type of cell is this? Give 2 reasons why you know this REVIEW

  12. What is this a picture of? What is this level of organization made up of? REVIEW

  13. What is the name of this process? Will water move in or out of the cell? How do you know this? REVIEW

  14. What type of reproduction is this? How do you know that? REVIEW

  15. What type of asexual reproduction is shown? Explain what is occurring REVIEW

  16. This is an example of a phase for what process? What are the stages of this process in order? REVIEW

  17. Explain what type of reproduction this is and why REVIEW

  18. Photosynthesis 1. DEF: Energy converting, food making process in green plants Photosynthesis

  19. Photosynthesis 2. Plants take in: Sunlight- captured by chlorophyll Carbon dioxide- enters through stomata Water- in through roots Photosynthesis

  20. Photosynthesis 3. Occurs in the chloroplasts Photosynthesis

  21. Photosynthesis 4. Plants then produce: Food- glucose (sugar used for starches, fats) Oxygen Photosynthesis

  22. Photosynthesis 5. Equation: Carbon dioxide + water + sunlight ---> glucose + oxygen CO2 + H20 + sun ---> C6H12O6 + O2 Photosynthesis

  23. Photosynthesis 6. Autotrophs- organisms that produce their own food Green plants Algae Photosynthesis

  24. Respiration 1. DEF: simple food substances (glucose) broken down and combined with oxygen to release energy in animals Respiration

  25. Respiration 2. Animals take in: Oxygen (inhaled) Glucose (food) Respiration

  26. Respiration 3. Occurs in Mitochondria Respiration

  27. Respiration 4. Animals produce/release these “wastes” Carbon dioxide (exhaled) Water Energy (ATP) Respiration

  28. Respiration 5. Equation: Glucose + Oxygen ---> carbon dioxide + water + ATP C6H12O6 + O2 ---> CO2 + H2O + ATP Respiration

  29. Respiration 6. Heterotrophs- organisms that cannot produce their own food- must eat other organisms to obtain the energy Respiration

  30. Create a T-chart by answering these questions for both photosynthesis and respiration • 1. In what types of organisms? • 2. In what cellular organelle does it take place? • 3. What is taken in/needed? • 4. What is produced/released? • 5. Equations

  31. O2-CO2 Cycle • The processes of photosynthesis and respiration create an oxygen- carbon dioxide cycling between plants and animals • Create a picture in your notebook to illustrate this cycle

  32. O2-CO2 Cycle

  33. Homework • Write the following assignment in your agenda: • Photosynthesis-Respiration Packet
