  1. Wonderful World of Bacteria

  2. The Cell • The cell is a unit of organization • Cells are classified as prokaryotes or eukaryotes • Living things are classified in six kingdoms based on structure.

  3. Prokaryotes • Within prokaryotes, there are two groups: Bacteria and Archaea.

  4. Meanings • Prokaryotes • Pro = Before • Karyote = Cell Nucleus • Do Not Have a Nucleus • Eukaryotes • Eu = True • Karyote = Cell Nucleus • Has a Nucleus Which is older Prokaryotes or Eukaryotes? Prokaryotes

  5. Examples • Example of Prokaryote • Bacteria • Example of Eukaryote • Animals, Plants, Fungi

  6. Kingdom Bacteria • Classified by how they get food. • Consumers obtain nutrients from other organisms.

  7. Bacteria • Most consumers are decomposers which feed on dead organic matter. • Parasitic is another consumer which means they invade the body of another organism to obtain food. • Bacteria who make their own food are producers. • Some are photosynthetic and chlorophyll is needed for photosynthesis.

  8. They are in our foods… BACTERIA are helpful because…

  9. Bacteria Movement • What is a that tail-like structure? • Its called a flagellum • A Flagellum is a whip like structure that propels bacteria forward. • Flagellum means whip in Latin

  10. More bacteria in our food…

  11. Medicines

  12. PseudomonaandPenicilliumand the help during oil spill clean-up

  13. Good For World • Nitrogen-fixing bacteria consume nitrogen in the air and change it into a form that plants can use. • Decomposing bacteria break down dead organic matter and make nutrients available again to living things. • Bioremediation is the use of bacteria and other microorganisms to change pollutants into harmless chemicals.

  14. Good For People • Some bacteria cause diseases while others make chemicals to treat diseases. • Antibiotics are medicines used to kill bacteria and other microorganisms. • Bacteria can also be bred for food! • Cheese • Yogurt • Buttermilk • Sour cream

  15. ARCHAEBACTERA • Bacteria that live in extreme conditions • The four main types of Archaebacteria: cold lovers, salt lovers, heat lovers, methane makers

  16. Deep Sea Vents Cold Lovers

  17. Hot SpringsHeat Lovers

  18. Salty EnvironmentsSalt Lovers

  19. Sewage PlantsMethane Makers

  20. Bacteria can also be harmful

  21. Bad Bacteria • Certain bacteria act as pathogens and cause tetanus, typhoid fever, pneumonia, syphilis, cholera, food-borne illness and tuberculosis. • Streptococcus bacteria may cause small infections like strep throat and some serious diseases like pneumonia. Certain streptococci may be fatal.

  22. Still More • Harmful bacteria in food cause botulism, which can cause paralysis or even death if even one-millionth of the bacterium is ingested. • Bubonic plague, is a rod-shaped type of bacterium which is well-known for its harmful nature. Bacteria-carrying fleas found on animals such as rats and mice transmit the bacteria that are believed to have caused the deaths of millions of people in human history

  23. Shape of Bacteria Cocci Bacilli or Rod Spirilla

  24. Most common and Least Common • The most common form of bacteria is Rod or Bacilli • The least common shape of bacteria is Spirilla
