1. MICROORGANISM AND THEIR EFFCTS ON LIVING THING CHAPTER 1

2. MICROORGANISM……? Micro and Makro?

3. Micro mean……………. small, very small, can’t see by naked eyes. Makro mean…………… big,can see by naked eyes

4. How to see the tiny particle such as microorganism….. It can be seen by using electron microscope..

5. The classification of microorganism.

6. The characteristic of microorganism include their… Appearance ---- keadaanluaran Shape……………….. Bentuk Size…………………… saiz Method of reproduction……………..caramembiak Nutrition ……………………. Nutrisi Habitat……………………….. Tempattinggal

7. Viruses

8. APPEARANCE OF VIRUSES Is the smallest microorganism The structure is simple Viruses consist (mengandungi) of strands of nucleic acid (DNA) which protected(dilindungi) by a protein coat

9. SIZE OF VIRUSES THE SIZE ARE TOO SMALL SMALLER THAN BACTERIA

10. SHAPE OF VIRUSES HELICAL POLYHEDRAL

12. CHARACTERISTIC OF VIRUS Viruses do not make their own food They obtain (mendapatkan) food from animals,plants and some bacteria. So they are PARASITES (mendapatmakanandrindividu lain sehinggamembawakeburukankepadaindividutersebut) The cell where the viruses are attached (melekat) are called as host cells… This cell become the habitat of the viruses

13. Viruses and host cell

14. Viruses are parasites… They can infect Human Animal Plant Bacteria

15. Viruses Infected on human

16. Viruses Infected on animal

17. Viruses infected on plant

18. Method of reproduction It only reproduce when it is contact with living cell.

24. BACTERIA Can be found everywhere They are the simplest single celled organism

25. Appearance

26. Appearance of bacteria Surrounded with tough cell wall cell wall …… support and maintain the shape of the cell Have hundred of hairlike called PILLI pilli……… enable(membolehkan) bacteria to stick (melekat) to certain surface (permukaan) Also have a tail tail……….. Help them to move

27. Size The size is bigger than viruses..

28. Shape of bacteria

30. Nutrition Carry out photosynthesis Some live as parasites Some are SAPROTROPHS… saprotrophs…absorb (serap) nutrient from dead organism

31. Method of reproduction By binary fission

32. Habitat

33. PROTOZOA

34. PROTOZOA Are unicellular microscopic organism They have complex internal structures such as nuclei containing genetic material

35. Size of protozoa Ranges from 5 to 250 µm So they are easily seen under low magnification microscope.

36. Example of protozoa

37. HABITAT AMOEBA Soil Fresh water Ocean Other organism as parasites PARAMESIUM Fresh water

38. Shape of AMOEBA Does not have fix shape Its shapes change when it moves Use PSEUDOPODIA which help them to move And use PSEUDOPODIA to capture and engulf(telan) makanan.

39. Shape like a slipper Has a tiny hair called CILIA CILIA was used to move and draw food into its body. SHAPE OF PARAMESIUM

40. METHOD OF REPRODUCTION AMOEBA Binary fission PARAMESIUM Binary fission

41. ALGAE

43. They have chlorophyll but it is not a plant….

44. Did algae have roots, stems and leaves?

45. They didn’t have roots, stems and leaves..

48. Method of reproduction They reproduce asexually through BINARY FISSION SPIRIGYRA reproduce SEXUALLY through CONJUGATION

49. CONJUGATION TWO individual united by a tube formed by outgrowths from one or both of the cells. Genetic materials are passed through the tube into the other cell.

50. CONJUGATION

51. and finally it will form 4 daughter cells

52. HABITAT

53. Fungi

56. Fungi Are simple, plant like organism Do not contain the chlorophyll Feed (mendapatmakanan) on the dead matter

57. Size The size ranges from 10 to 100µm Example of fungi… Mould Yeast

60. Habitat of fungi
