  3. What does it take to grow a plant???

  4. How do we grow a plant? But is that all????

  5. Photosynthesis

  6. Photosynthesis

  7. Photosynthesis

  8. Photosynthesis Sunlight (light Energy) Carbon Dioxide CO2 Water H2O

  9. Photosynthesis Sunlight (Light Energy) Glucose C6H12O6 Water H2O Oxygen O2 Carbon Dioxide CO2

  10. Photosynthesis

  11. Photosynthesis Sunlight (Light Energy) Glucose C6H12O6 Water H2O Oxygen O2 Carbon Dioxide CO2

  12. Photosynthesis • Let’s write the chemical equation on the board!! • What are the reactants, What are the products? • What type of energy transformations are going on?

  13. Cell Respiration Carbon Dioxide CO2 Glucose C6H12O6 Water H2O Oxygen O2 Energy

  14. Cell Respiration Carbon Dioxide CO2 Glucose C6H12O6 Water H2O Oxygen O2 Energy

  15. Cell Respiration • Let’s draw the chemical formula on the board!! • What are the reactants, What are the products? • What type of energy transformations are going on?

  16. It’s a cycle in plant cells, Jennnnay

  17. The process of cellular respiration is taking place in your cells right now!! • You are currently taking in oxygen and burning sugars within the mitochondria to release chemical energy. • This process is also known as Aerobic Respiration. Why? • Because Oxygen is present which allows your cells to burn glucose into energy much more efficiently. • I am sure you have heard of Aerobics.

  18. What would happen if your cells were deprived of oxygen?? Would they still be able to burn glucose to make energy?? • YES!! • Fermentation • When might this occur? • Long distance runners often create an anaerobic environment for their cells • What does anaerobic mean?? • No Oxygen present • Not a very energy efficient process and a bad side effect is produced: • Lactic Acid

  19. A different example of fermentation • Breweries rely on this process: • Yeast cells need energy to survive, so they will breakdown sugars in anaerobic conditions and a byproduct is alcohol. • How do you know CO2 is produced?

  20. Based on the graph, what color is this plant: • Green • Red • Violet

  21. Based on the graph, what colors are best absorbed by this plant: • Green and orange • Red and violets • Violet and green 4. Green and reds

  22. Based on the graph below, which color light is least absorbed by plants for photosynthesis • Red • Yellow • Green • Orange • Violet

  23. What is this graph showing you?? pH

  24. A scientist wants to study photosynthesis in a newly discovered species. Which of these cell structures should the scientist study? • Vacuoles • Chloroplasts • Mitochondria • Ribosomes

  25. Muscle cells require more energy than do most other cells. Which organelles would you expect to find in greater abundance in muscle cells than in most other cells? • Cilia • Mitochondria • Ribosomes • Chloroplasts

  26. Which of these processes results in carbon dioxide production? • Osmosis • Respiration • Evaporation • Photosynthesis

  27. Some organisms that live in the intestines of cows do not require oxygen to survive. Which of these best describes the process by which these organisms obtain energy? • Osmosis • Mitosis • Cellular respiration • Fermentation
