  2. Protist and Bacteria 7.2.3 Compare the body shapes of bacteria (spiral, coccus, and bacillus) and the body structures that protists (euglena, paramecium, amoeba) use for food gathering and locomotion.

  3. Divide your paper

  4. Protist • http://teachertube.com/viewVideo.php?video_id=223926

  5. Protist • Protists are usually one celled organisms that live in all moist environments. • Classified by their locomotion (how they move) • We can Remember it as…. • Every Family ate Apple Pie and a Piece ofCake • Euglena-Flagella, Ameoba-Pseudopod, Paramecium-Cilia

  6. Protist

  7. Euglena—Protist with Flagella • move pulling themselves with long whip like structure called flagella.  • have one or more flagella that help them move. • The euglena is unique in that it has characteristics of both a plant and an animal, it contains chloroplasts that photosynthesize and also can consume other organisms as well.

  8. Paramecium—Protist with Cilia • beating tiny hair-like structures called cilia. • The cilia act as tiny oars that allow the protist to move through its watery environment. • The cilia also move and help to capture food directing in toward a groove that functions like a mouth.

  9. Amoeba—Protist with Pseudopods • extending their bodies forward and then pulling the rest of their bodies forward as well. • The finger-like structures that they project forward are called pseudopods (false foot).  • The pseudopods are also used to trap food.

  10. Bacteria are organisms that are classified into the Moneran Kingdom. They are all single-celled organisms. They are classified by their body shapes. • Spiralcorkscrew bacteria • Bacillus Rod-shaped bacteria • Coccus Round-shaped bacteria

  11. Bacteria • Classified by their body shape

  12. homework • Essentials book page 12 -17 • Do foldable • Draw illustrations for voc words

  13. bellringer • Draw petri dish and label in isn book

  14. Fun Facts! • Bacteria are about 1000 nanometres in size (a nanometre is one millionth of a millimetre). • People have more bacterial cells in their bodies than human cells – and more than there are people on the planet. • Bacteria (usually dead or weak ones) are used to make vaccines. • It is estimated that 500 to 1000 species of bacteria live in the human gutand a roughly similar number on the skin. • Theodor Rosebury estimates that there are 10 million individual bacteria living on the average square centimeter of human skin.

  15. Warm-up What do you know about bacteria and viruses? Make a List!

  16. Viruses • Viruses are tiny particles much smaller than bacteria and can only be seen with a very powerful microscope. • In isolation, viruses show none of the expected signs of life. They do not respond to stimuli, they do not grow; they do not do any of the things we normally associate with life. • Therefore, they should not be considered as living organisms at all. • However, viruses do show one of the most important signs of life: the ability to reproduce. • Viruses are considered to be nonliving until they infect the cells of a host plant or animal and reproduce within those cells. • Viruses are responsible for causing many diseases in living organisms (for example AIDS, colds, and flu in humans).

  17. Viral vs. Bacteria • Simply put, bacterial infections are caused by bacteria and viral infections are caused by viruses. Infections caused by bacteria include strep throat, tuberculosis and urinary tract infections. Diseases that result from viruses include chickenpox, AIDS and the common cold. • antibiotic drugs usually kill bacteria, but they aren't effective against viruses. In some cases, it may be difficult to determine whether bacteria or a virus is causing your symptoms. Many ailments — such as pneumonia, meningitis and diarrhea — can be caused by either type of microbe.
