Moneran Kingdom

  1. 1. Moneran Kingdom Bacteria and Viruses
  2. 2. Part 1 Characteristics of monerans and viruses.
  3. 3. Moneran Kingdom <ul><li>Monerans are one celled organisms. </li></ul><ul><li>They exist anywhere life can be found and can live in really high or low temperatures. </li></ul><ul><li>They have a cytoplasm, a cell wall, a cell membrane, and chromosomes. A major difference is that a moneran cell lacks a nucleus. </li></ul><ul><li>Many do not move on their own, however, some have a flagella for movement. </li></ul>
  4. 4. Bacteria <ul><li>Bacteria, a kind of moneran, feed on dead or decaying matter and on living things. </li></ul><ul><li>Bacteria are classified into three groups according to shape. </li></ul>Spiral Spherical Rod-shaped Spirillum Coccus Bacillus
  5. 5. Blue-Green Bacteria <ul><li>Blue-green bacteria are monerans that contain chlorophyll. </li></ul><ul><li>They make their own food. </li></ul>
  6. 6. Moneran Reproduction <ul><li>Monerans reproduce by fission. </li></ul><ul><li>Under ideal conditions they can reproduce every 20 minutes </li></ul>
  7. 7. Part 2 Viruses
  8. 8. Virus <ul><li>A virus is a tiny fragment of genetic material wrapped inside a tiny capsule, or coating, of protein. </li></ul><ul><li>Viruses reproduce inside another cell or host organism. </li></ul><ul><li>Viruses are only active in the cells of other living things. </li></ul><ul><li>Some examples of viruses are: the flu, polio, and AIDS </li></ul>
  9. 9. Viral Reproduction <ul><li>1. The virus attaches itself to the cell wall. </li></ul><ul><li>2. Then it injects genetic material into the cell. </li></ul><ul><li>3. The genetic material takes control of the cell. </li></ul><ul><li>4. The cell stops its normal function and starts to produce more viruses. </li></ul><ul><li>5. The cell becomes filled with viruses </li></ul><ul><li>6. The cell finally bursts and the process repeats itself. </li></ul>1 2 3 4 5 6
  10. 10. Part 3 Bacterial and Viral Diseases
  11. 11. Communicable Disease <ul><li>A communicable disease is one in which the disease-causing organism is passed from one host to another by direct or indirect contact. </li></ul><ul><li>When the disease-causing bacteria gets into the body it causes an infection. </li></ul>
  12. 12. Toxins <ul><li>Toxins are produced by bacteria. </li></ul><ul><li>Toxins are chemical poisons that are harmful to the body. </li></ul>
  13. 13. Immune System <ul><li>An immune system is the body system that defends against disease. </li></ul><ul><li>The main line of defenses in this system are the white blood cells. Some white blood cells actually eat bacteria. </li></ul><ul><li>Other white blood cells produce antibodies. An antibody is a protein that attaches itself to bacteria in order to destroy it. </li></ul>
  14. 14. Medicines <ul><li>Antibiotics are used to stop the growth and reproduction of bacteria. </li></ul><ul><li>Many antibiotics are produced from other microbes and from fungi. </li></ul><ul><li>A vaccine is a mixture of weakened or dead disease-causing microbes that cause the body to produce antibodies in order to fight off infection before it begins. </li></ul>
  15. 15. HIV / AIDS <ul><li>HIV is the virus that cause AIDS. HIV attacks the body’s immune system making it weak and prone to infection. </li></ul><ul><li>It is hard to find a cure or vaccine for AIDS because it is constantly evolving and can live in a person’s cells for years. </li></ul><ul><li>Scientist are currently treating HIV with a variety of medicines. They are also trying to inject HIV genetic material into another virus with hope that the host will develop an immunity to both viruses. </li></ul>
  16. 16. Helpful Bacteria <ul><li>Remember, bacteria is used in many types of food production. Including: cheese, pickles, yogurt, butter, sour cream, chocolate, and many more. </li></ul><ul><li>Bacteria can also help the body digest food and produce certain vitamins. </li></ul><ul><li>Some bacteria fight off diseases. For example insulin is used to treat people with diabetes. </li></ul><ul><li>Most importantly, bacteria helps to break down all the dead plant and animal remains making nutrients for the soil. Without this process the world would become quickly polluted with these materials. </li></ul>
