E coli

  1. 1. Escherichia Coli By: Joe Chandler S
  2. 2. Characteristics of All Living ThingsS As we learned this week, all living things grow, reproduce, react, and they have cellular organization. Bacteria show all of these traits in different ways depending on the type.S Growth
  3. 3. ShapesS Bacteria come in three main shapes, bacilli, or rod shaped, cocci, or spheres, and spirilla, which are in a spiral shape. These differently shaped bacteria can group together in all kinds of different ways.
  4. 4. Escherichia ColiS Escherichia Coli or E Coli, is a bacteria that lives in the intestines of most animals. It provides us with vitamin K, which helps us break down certain proteins that help with the clotting of blood. It was first discovered or identified in 1885 by Theodore Escherich from Germany.
  5. 5. ResponseS E Coli responds to a sudden increase in temperature by overproducing a protein the posses.
  6. 6. ReproductionS E Coli, like many other bacteria, uses binary fission to reproduce. This is how binary fission works.
  7. 7. GrowthS This reproductive cycle from the page before shows the growth of cells like E Coli as well as their reproduction.
  8. 8. OrganizationS E Coli is a single celled organism, so the one cell is the arrangement or organization. Each E Coli cell is about 2 micrometers long and rod shaped. A micrometer is one millionth of as meter, so you have to use a microscope to see it.
  9. 9. What Makes E Coli Different Than Other Organisms?S First off, all bacteria like E Coli don’t have a nucleus, all genetic material is contained in loops inside the cell. E Coli and bacteria related to it have the ability to transfer DNA through bacterial conjugation, or the transfer of DNA just by contact with another cell ,and transduction or the transfer of DNA from one bacterial cell to another cell because of a virus.
