Name: ________________________________ Hour:___________ Bacteria vs. Virus KWL Chart Biology A/Cells Directions: 1) Think about bacteria and viruses (What do you know about bacteria and viruses? How are they similar? How are they different? What do they look like? What do they do? Can you think of any specific examples?) 2) Complete columns 1 and 2 of the following chart. 3) Read the attached article “ Bacteria vs. Viruses” 4) Complete column 3 of the chart What I Know about Bacteria and Viruses What I Want to Know about Bacteria and Viruses What I Learned about Bacteria and Viruses "Bacteria vs. Viruses" Jose Reyes: http://cubanology.com/Articles/Virus_vs_Bacteria.htm Directions: 1) Complete columns 1 and 2 in your Bacteria and Virus KWL Chart. 2) Read this article carefully 3) Complete column 2 in your Bacteria and Virus KWL Chart Bacteria Definition: Bacteria is plural for Bacterium. A bacterium is a microbe (a microscopic single cell organism) that can be found virtually anywhere. They are in air, the soil, and water, and in and on plants and animals. Function: There are good and bad bacteria. They have useful functions like: making vitamins, breaking down garbage, and even maintaining our atmosphere. The human mouth is home to more than 500 species of bacteria. The more we know about bacteria, the more we are able to figure out how to make microbes work for us or stop dangerous ones from causing serious harm. Appearance: A Bacterium consists of a single cell. " Barrelia Burgdorferi" Bacteria" "Gillionella Bacteria" "Anebena Diseases caused by Bacteria: Bacillus Anthracis (Anthrax) Escherichia Coli (E. Coli-a food born sickness in stomach) Microbacterium tuberculosis (Tuberculosis) Streptococcus pneumoniae (Strep Throat, Meningitis, and Pneumonia) Virus Definition: Viruses are the simplest and tiniest of microbes. They can be as much as 10,000 times smaller than Bacteria. Viruses consist of a small collection of genetic material (DNA or RNA) encased in a protective coat called a capsid. Function: When viruses come into contact with the “host cells” (such as normal human cells), they trigger the cells to engulf them and connect themselves so they can release their genetic material (DNA) into the cell. Once inside a host cell, viruses take over its machinery to reproduce. Once this occurs, the virus then overrides the host cell's normal functions with their own set of instructions which shut down the production of the host cell’s proteins and direct the cell to produce viral proteins to make new viruses. Some viruses insert their genetic material into the host cell's DNA, where they begin directing the copying of their genes or simply lie asleep for years or a lifetime. Either way, the host cell does all the actual work, the viruses simply provide the instructions. Appearance: West Nile Virus Virus) Orthomyoxovirus (Influenza) Hepatitus B Virus "Rotavirus" (Stomach Human Immunodeficiency Virus (HIV) Diseases caused by Viruses: Human Immunodeficiency Virus (HIV) Human Papilloma Virus: (Gential Warts, which can lead to cervical cancer) Influenza (The Flu) Viriola Major (Smallpox)
