Presentation Transcript

  1. The start of a food chain. Energy from the sun comes to earth as light.

  2. Algae and Green leaves have cells which contain a green pigment called chlorophyll

  3. Chlorophyll in the cells of living algae will trap some of the energy from sunlight

  4. Chlorophyll in the cells of living leaves will trap some of the energy from sunlight

  5. Chlorophyll inside leaf cells. The chlorophyll packets are called chloroplasts

  6. The chloroplasts is where food is produced… (where sugar is made )You are looing at the place where most food chains start!

  7. During Photosynthesis the energy from sunlight is trapped by green chlorophyll and then the energy is stored inside a carbohydrate called GLUCOSE SUGAR

  8. This process is called PHOTOSYNTHESIS

  9. Glucose sugar is made out of Water and Carbon Dioxide

  10. A leaf is designed to bring together 3 ingredients. CO2, H20, and light • co

  11. Air Enters and leaves a leaf through tiny openings called Stomata. CO2 in…. O2 OUT

  12. Water is carried in small tubes from root to leaf. We see the tubes as leaf veins

  13. Thin leaves allow light to penetrate and hit chlorophyll

  14. Photosynthesis is all about making a sugar called GLUCOSE … C6 H12 06

  15. The equation for Photosynthesis

  16. Energy from the sun is now stored in the sugar Energy is measured in calories

  17. Made from CO2 and Water… with sunlight stored inside! ( calories )

  18. During Photosynthesis… carbon dioxide is removed from the air and used to make sugar.

  19. During Photosynthesis oxygen is released to the air

  20. PLANT CELLS run on energy stored in glucose sugar

  21. Animal Cells run on the energy stored in Glucose

  22. Model of a Glucose sugar molecule.C6 H12 O6

  23. The sun’s energy is now stored in the bonds of glucose sugar

  24. GLUCOSE is THE SUGAR • We can make all other foods ( Fats / Oils / Protein / Starch etc.. From Glucose sugar. This means that a food chain is driven by Glucose!

  25. STARCH IS GLUCOSEmolecules hooked together like train cars

  26. STARCH

  27. The only way energy gets into the bonds of glucose on the earth’s surface
