  4. Autotropic W1 S8S1SCCH4-microorganism-Day5 • P/ Auto-tro-pic • M/ organisms that are able to make energy-containing organic molecules from inorganic raw material by using basic energy sources such as sunlight.  Gajwani Schools and Colleges

  5. Autrotopic W1 S8S1SCCH4-microorganism-Day5 • A/ Some, but not all, archaebacteria are chemosynthetic autotrophs. ******* Gajwani Schools and Colleges

  6. Turbid W2 S8S1SCCH4-microorganism-Day5 • P/ Tur-bid • M/  opaque, or thick with suspended matter. ******* Gajwani Schools and Colleges

  7. Turbid W2 S8S1SCCH4-microorganism-Day5 • A/ Turbid ice is widespread but not universally present. ******* Gajwani Schools and Colleges

  8. What are Viruses A virus is a non-cellular particle made up of genetic material and protein that can invade living cells.

  9. The Structure Of a Virus • Viruses are composed of a core of nucleic acid • The Nucleic acid core is surrounded by a protein coat called a caspid

  10. Who gets them? • Mammals and birds • amphibians, reptiles and fish • plants and fungi • insects

  11. Most viruses are species specific • Most, but not all And of course, in us humans…

  12. How do viruses cause disease? • by damaging/killing cells outright • by inducing immunopathology • by transforming cells

  13. Vaccines • Viruses grown on chicken embryos are attenuated vaccines • Another type of vaccine is made by heat killing the virus

  14. Diseases caused by virus • Measles • Viral haemorrhagic fever • Rabies

  15. Immunity W1 S8S1SCCH4-microorganism-Day5 • P/ Immu-nity • M/ the ability of an organism to resist a particular infection or toxin by the action of specific antibodies or sensitized white blood cells. Gajwani Schools and Colleges

  16. Immunity W1 S8S1SCCH4-microorganism-Day5 • A/ Vaccines depend on them, and scientists are even employing the cells to stir up immunity against cancer. Gajwani Schools and Colleges

  17. Inactive W2 S8S1SCCH4-microorganism-Day5 • P/ In-active • M/ not engaging in or involving any or much physical activity. Gajwani Schools and Colleges

  18. Inactive W2 S8S1SCCH4-microorganism-Day5 • A/ By failing to buy insurance, an individual is merely inactive. Gajwani Schools and Colleges

  20. QUESTION 2 Q2: S8S1SCCH4-microorganism-Day5 Write diseases caused by virus? Ans : Measles Viral haemorrhagic fever Rabies Gajwani Schools and Colleges

  21. QUESTION 3 Q3: S8S1SCCH4-microorganism-Day5 • How do virus cause disease? • Ans :by damaging/killing cells outright • by inducing immuno-pathology • by transforming cells Gajwani Schools and Colleges
