Resource summary

  1. Mircobiology- The Study of Living things.
    1. Micro-Organisms( also called Microbes) are too small to be seen by the naked eye and are found in huge numbers almost everywhere.
      1. They are present in the Air, Water and Soil, on our skin and inside plants, animals and humans.
        1. There are three types of Micro-organisms.
          1. Viruses
            1. Bacteria
              1. Fungi
            2. Viruses
              1. Viruses are the smallest micro-organisms
                1. Viruses cannot reproduce themselves( they use our cells to multiply, they need a host)
                  1. All Viruses are said to be parasites(I.E. They live on or in another living thing)
                    1. Viruses cause disease to plants, humans and other animals.
                      1. Virus Diseases
                        1. Measles
                          1. Mumps
                            1. Chicken Pox
                              1. Pollo
                                1. Common Cold
                                  1. Flu(Influenza)
                                    1. Cold Sores
                                      1. AIDs(Caused by HIV)
                                      2. Very few chemicals or medicines can kill viruses, for example, Antibiotics prevent bacterial infections but have no effect on viruses as viruses are parasites and use other cells to multiply.
                                        1. Our bodies fight off most virus infections when our White blood cells produce chemicals called Antibodies.
                                        2. Bacteria
                                          1. Bacteria are larger than viruses
                                            1. They don't have a proper Nulceus
                                              1. In order to grow they require
                                                1. Food

                                                        1. In asexual reproduction the offsprings are to the parent as they only came from one parent.
                                                          1. There are no sex cells (Gametes) involved.
                                                            1. Useful
