1. BACTERIA

2. Part of the Moneran Kingdom One celled organism that lacks a nucleus they do however have nuclear material within the cell wall

3. TRAITS

4. One celled monerans Larger than viruses Live in water, soil, food EVERYWHERE Shapes ROUND, SPIRAL, ROD No nucleus 1 main chronmosome Cell wall Cell membrane Reproduce, grow, carry out cellular respiration

5. MORE TRAITS

6. Sticky outer layer Flagellum---whip-like thread Reproduce by fission(asexual) divide into 2 organisms Chromosome parts make a copy of itself then the cell divides Bacteria need moisture, certain temperature, and food to survive

7. TYPES OF BACTERIA

8. PARASITES AND SAPROPHYTES Parasites feed on living things Saprophytes feed on dead material

9. BACTERIA AND DISEASE

10. Human diseases caused by bacteria Strep throat Tuberculosis Certain kinds of pneumonia gonorrhea

15. BACTERIA CAN BE SPREAD By touching anything that is infected Clothes, silverware, food drinking water Sexual contact Syphilis Gonorrhea Insects, cockroaches, flies and mosquitoes

16. HELPFUL BACTERIA

17. Bacteria is needed to decompose dead matter

18. Bacteria in our stomachs and intestines help make vitamins that we need To help make linen, rope Antibiotics which are chemical substances that kill or slow the growth of bacteria

19. BACTERIA AND FOOD Cottage cheese Swiss chese Sour cream Butter milk Sauerkraut Vinegar yogurt

20. CONTROLLING BACTERIA High heat (boiling) Pasteurization(heating milk) Refrigeration Freezing (slow growth) Dehydration take water out of food(noodles, cereal) Antiseptics kill bacteria on living things and prevents infection Disinfectants kill bacteria on non-living things –
