2. Welcome to

3. Today’s exciting topics…. Living Things, Domains and Kingdoms, and Bacteria !

4. Classification of Living Things Bacteria 101 Anything Goes! Domains and Kingdoms Characteristics of Living Things Bacteria True/False 100 200 300 400 500 PowerPoint Jeopardy

5. Bacteria are prokaryotic. What does this mean?

6. Prokaryotic means that a cell does not have a nucleus or any other membrane bound organelles. Back to Game Board

7. Bacteria have been divided into two domains. Name the two domains of bacteria.

8. Domain Archaea Domain Bacteria Back to Game Board

9. To what kingdom do the “true” or common bacteria belong?

10. Kingdom Eubacteria Back to Game Board

11. The ancient forms of bacteria that can survive in very hostile environments belong to what kingdom?

12. Kingdom Archaebacteria Back to Game Board

13. One of the ways that the bacteria are separated into two different domains is based on the chemical composition of their cell walls. Are the cell walls of Archaea similar or different from Eubacteria?

14. different Back to Game Board

15. Identify the structure below. What is its function?

16. 1) The structure is flagella. 2) Its function is to help the bacteria move. Back to Game Board

17. These pictures represent the three different shapes of bacteria. Even though the shapes are different, name 2 ways they are all similar. coccus (sphere shape) bacilli (rod shape) Spirillium (spiral shape)

18. 1) They are single –celled. 2) They are prokaryotes(lack nucleus). 3) They are in the Bacteria Kingdom. Back to Game Board

19. You have been asked to investigate a new species. It has : 1) It has only 1 cell 2) no nucleus 3) is found on areas where eubacteria are found. 4) It grows when placed in sunlight. What cell type is it ? _____________________ What cell number is it ?___________________ Is it able to make its own food? _____________ What is that called?_______________________

20. prokarote unicellular sunlight autotoph Back to Game Board

21. Look at the picture below. What type of bacterial reproduction is it? Both names, please.

22. Asexual or binary fission Back to Game Board

23. List two reasons why bacteria are important to humans.

24. They are important as decomposers (breakdown of dead organisms. They are used to make a variety of foods (yogurt, sour cream, cheese, etc.) Located in stomach to help animals digest their food. Back to Game Board

25. An new organism was found in the Amazon jungle- it is multicellular. To what domain does it probably belong ?

26. Eukaryote, because all multicellular organisms have a nucleus. Back to Game Board

27. Bacteria reproduce most often by binary fission. Describe this process.

28. During binary fission a single cell divides to form two identical cells. It is asexual reproduction. Back to Game Board

29. Look at the photo below. What type of organism is most likely to live there? Why?

30. Back to Game Board Archaea, because they are most likely to live in extreme environments.

31. In order to be considered part of a species you must have 3 things. What are they?

32. 1.Must have similar characteristics. 2.Must be able to produce fertile offspring. 3. Must have similar DNA. Back to Game Board

33. The scientific study of how living things are classified is called ____________.

34. Taxonomy. Back to Game Board

35. Both Archaea and Eubacteria have similar characteristics. Name 2 of them.

36. 1)They are prokaryotes 2)They are unicellular 3)They may be autotrophs or heterotrophs. 4)They have been on Earth for billions of years. Back to Game Board

37. What name is given to the short sticky structures that help attach a bacterium to a food source or to another bacterium?

38. pilus Back to Game Board

39. Is the DNA of Bacteria contained in a nucleus?

40. No, that is why they are called prokaryotes (before nucleus). It is a single, circular strand of DNA. Back to Game Board

41. Which is not one of the 4 kingdoms of eukaryotes? 1)fungi 2)protists 3)archaea 4)plants

42. 3) archaea. They are prokaryotes. Back to Game Board

43. The process of change that occurs in an organism’s life to produce a more complex organism is called : 1)Response 2)Development 3)Evolution 4)growth

44. Back to Game Board

45. What name is given to an organism that lives on dead, decaying matter?

46. decomposer Back to Game Board

47. You are investigating a new species found on the forest floor. It is a heterotroph, unicellular, and has a nucleus. To what kingdom does it probably belong?

48. Fungi Back to Game Board

49. What name is given to an organism that uses sunlight as a source of energy to build molecules of glucose?

50. Autotroph Back to Game Board

51. The 2 kingdoms that contain only heterotrophs are animals and: 1)Archaea 2)Fungi 3)Protists 4)bacteria

52. Back to Game Board 2) Fungi

53. Are some bacteria autotrophs and some heterotrophs?

54. Yes, some are autotrophs (plant-like) and some are heterotrophs (animal-like). Back to Game Board

55. True of False? All bacteria cause diseases.

56. False Most bacteria are beneficial or benign. Back to Game Board

57. Bacteria can reproduce at an amazing rate, doubling their numbers by cell division every 20 minutes.

58. True Back to Game Board

59. An organism that is made up of many cells is unicellular. True or False?

60. False. That would be multicellular. Back to Game Board

61. An organism whose cells contain a nucleus is a eukaryote. True or False?

62. True Back to Game Board

63. The 6 characteristics of living things are: 1)Have cells 2)The ability to move 3)Obtain and use energy 4) Respond to their environment 5) Grow and develop 6) Have chemicals of life

64. False 2) Movement is not a characteristic of living things. * The missing characteristic is reproduction. Back to Game Board
