Presentation Transcript

  1. What are autotrophs?

  2. Organisms that make their own food (like plants)

  3. What do autotrophs need to make their own food?

  4. Sunlight  photosynthesis

  5. What are the products of photosynthesis?

  6. Glucose and oxygen

  7. How do all organisms obtain energy?

  8. by absorbing nutrients from food we eat (not by digesting it)

  9. What are the reactants of photosynthesis?

  10. Carbon dioxide and water (combined with sunlight and chlorophyll)

  11. What are heterotrophs?

  12. Organisms that cannot make their own food (like animals)sHeterotrophs are consumers - they must obtain their food by consuming producers or other consumers

  13. What is the formula for photosynthesis?

  14. (with sunlight and chlorophyll)

  15. What are the 2 basic forms of energy?

  16. Kinetic – movement Potential energy – based on position

  17. Give an example of when you would have high kinetic energy + high potential energy.

  18. Going up stairs or roller coaster (the potential energy increases as you go up)

  19. What is cellular respiration?

  20. Harvesting energy (ATP) stored in food – occurs in both plants and animals

  21. What are the reactants and products in cellular respiration?

  22. Opposite to photosynthesis:Glucose and oxygen  Carbon dioxide, water and ATP

  23. What is the formula for cellular respiration?

  24. What is chemical energy?

  25. The potential energy of organic compounds – related to the arrangement of the atoms within amolecule. (see peanut diagram)

  26. What is a calorie?

  27. A unit of energy – the amount of energy required to raise the temperature of 1 gram of water 1 degree Celsius

  28. What is deceptive about the number of calories on a food label?

  29. 1 kilocalorie=1000 calories called “big C”The calories shown on a food label is are kilocalories

  30. What is thermal energy?

  31. energy transferred from a warmer object to a cooler object – heat that cannot be saved or collected

  32. Give an example of thermal energy

  33. 1- About 75% of all the available energy in gasoline is lost as heat. 2-60% of heat is lost from the human body – this is why we get hot in a small crowded room.

  34. What is the structure of Chloroplasts?

  35. Where photosynthesis takes place in plants

  36. Where do Oxygen, CO2 (gases) and water leave the leaves from in plant leaves?

  37. Stomata – like a door on the underside of a leaf

  38. What is the liquid inside a chloroplast called?

  39. stroma

  40. Coin-like structures that are found in the stroma

  41. Thylakoid

  42. In a leaf, where are the greatest number of chloroplasts found?

  43. Facing the sun (on top)

  44. The chlorophyll uses “this” along with carbon dioxide and hydrogen ions to produce sugar molecules

  45. Energetic electrons

  46. What are the 2 stages of photosynthesis

  47. Light and dark reactions (dark reactions are also called the Calvin Cycle)

  48. What does ATP stand for?
