  1. Bacteria Mr. J

  2. Objective for this section: (copy) • Students will be able to: • Describe ways in which bacteria cells are different than other organisms & viruses. • List positive roles bacteria play in society. • Name the three main types of bacteria, the two kingdoms of bacteria, and explain how bacteria reproduce and survive.

  3. Opening Assignment A: • List ways you believe that bacteria are the same and different from other organisms.

  4. Opening Assignment B: • Vocabulary Explosion

  5. Three Shapes of Bacteria Spherical (Cocci) Rod (Bacilli) Spiral (Spirilla)

  6. Controls the Bacteria’s functions Bacteria’s gel-like “blood” Creates proteins for the bacteria The controlling “filter” of the bacteria Serves as protection for the bacterial cell Helps the Bacteria move

  7. Which foods do you think were prepared with bacteria’s help?

  8. “Cheese Wiz” Microscope Assignment Mr. J

  9. Current Events: Bacteria ! • In this assignment you will use the website links to search for current events related to Bacteria. • You will then complete a W5 Breakdown: • Who wrote it • Where did it occur • When did it occur • What effects has it had on society • Why you think it relates to our current topic • Please speak clearly so that we may fully enjoy your awesomeness. • Please listen quietly so that others may enjoy the awesomeness. • We must limit each presentation to 10 min so that we may all share our awesomeness. • Mr. J may ask a brief a question bout your presentation’s awesomeness. • Your presentation will be graded based on the class rubric scale of Outstanding (10) ,Satisfactory (7) ,Needs Improvement (5) max = 10 points.

  10. Conjugation Station Mr. J

  11. Select Two Traits • Hot Water • Cold Water • Acidic Conditions • Limited Food • Sunlight • Pressure • Dry Conditions • Antibiotics

  12. Understanding Bacteria Video Assignment

  13. Challenge Questions • What are the shapes of bacterial cells? • Rod, Spiral, Sphere • What is found in the cytoplasm of bacterial cells? • Ribosomes & Genetic Material • What process results in genetically different bacteria? • Conjugation • When do endospores form? • During Harsh Conditions • What important role do decomposers play? • Break down chemicals and return nutrients to the soil

  14. Challenge Questions 6. Which bacterial part functions in protein production? • Ribosomes 7. Explain the difference between a heterotroph and autotroph: • Hetero-Consumes food / Auto- Makes its own food 8. What kind of process is Binary fission? • Reproduction 9. The process of breaking down food to release its energy is called: • Respiration 10. What structures are always found in bacterial cells for protection? • Cell wall

  15. Challenge Questions 11. Describe the difference between asexual and sexual reproduction: • Sexual involves two individuals/ Asexual one 12. Bacteria are either one of two things to humans what would these be: • Helpful or Harmful 13. What is the outermost structure of most bacterial cells called? • Cell Wall 14. Describe the function of the flagellum: • Transportation 15. Why are bacteria considered prokaryotes: • Its Genetic information is not contained in a nucleus

  16. Challenge Questions 16.What occurs when a bacterium transfers some of its genetic material to another bacterium? • Conjugation, which results in a genetically different bacteria. 17. What are chemicals like penicillin called that can kill bacteria? • Antibiotics 18. What must bacteria release when they break down food? • Energy

  17. Classifying Use what you know about viruses and bacteria to complete the following table. Mark an X in the box if the characteristic applies. A characteristic may apply to both When you have finished, add one characteristic that applies to viruses and one that applies to bacteria. Copy the chart and answer the questions:
