  1. Characteristics of all living things is that they all use… Energy

  2. Two ways organisms get their energy (food) • Autotophic • Heterotrophic

  3. Autotroph & Heterotropoh autos - Greek for “self” hetero – Greek for different trophos - Greek for “feed”

  4. Photoautotrophs

  5. Photoautotrophs

  6. BacteriaUsed to be in the Kingdom Monera. “moneres” means single. All bacteria are single celled.

  7. Are bacterial harmful ? Beneficial ? Both ?

  8. Bacteria – Domain Prokarya Kingdom Eubacteria First appeared in the Precambrian Era Cyanobacteria – Also Known as “blue green algae

  9. Cyanobacteria – Blue Green AlgaeThey are NOT algae!

  10. How Eubacteria are identified • Gram + bacteria turn purple when stained. Absorb a violet stain • Gram – bacteria appear pinkish when stained. Outer layer of carbohydrate and protein absorbs pinkcolor

  11. Can you identify the type of bacteria?

  12. Bacteria – Domain Prokarya Archaebacteria Methanogens produce methane gas

  13. The straight poop about cow poop! • Methanes heat trapping power is 21 times greater than carbon dioxide. • 1.3 billion cows. Global pop. of cows as doubled in the last 40 years • Methane gas levels have doubled in atmosphere • Cow expels 600 liters of methane a day!

  14. A crappy car?

  15. Cocci – Bacilli - Spirilla

  16. Bacteria Culture

  17. Kingdom ProtistaAlgae & Protozoans

  18. Plants – Nonvascular - Moss

  19. Vascular – Seedless - Ferns

  20. Vascular Plants with seeds

  21. What are the two most important products of photosynthesis? Glucose and Oxygen

  22. Lets take a close up look of the leaf.

  23. Cross-section of a leaf

  24. Chloroplast and Stomata

  25. Stoma means “mouth” What do you think passes through the stomata?

  26. When iodine comes in contact with starch it can turn

  27. Chloroplast

  28. What is needed for photosynthesis?

  29. Chlorophyll

  30. What is a pigment • Pigments are chemical compounds which reflect only certain wavelengths of visible light. This makes them appear "colorful". Flowers, corals, and even animal skin contain pigments which give them their colors.

  31. Pigments Absorb wavelengths of light • More important than their reflection of light is the ability of pigments to absorb certain wavelengths.

  32. What happens when chlorophyll absorbs sunlight energy?

  33. What else is needed for photosynthesis to occur?

  34. Only certain areas are exposed to sunlight

  35. Sunlight is needed !

  36. Visible Light

  37. VisibleLight

  38. Light is a form of energy that travels in waves !

  39. The difference between red and blue light is……..

  40. Which colors are the most and least important in photosynthesis ?

  41. Why? • The reason why red and blue is the most important is because they are absorbed by the pigment chlorophyll and green light is reflected

  42. Electromagnetic Energy

  43. Ingredients for photosynthesis..

  44. With carbon dioxide No carbon dioxide

  45. The 5 things needed for photosynthesis are….. • Chloroplast - Place • Sunlight - Energy • Chlorophyll – Captures the energy ! • Carbon Dioxide – 2 of the 3 elements needed to make glucose. C & O • Water – Electron and hydrogen

  46. What is produced in photosynthesis ?

  47. What is in the empty part of the test tube ?
