Escherichia coli (E. coli) is a bacterium that lives in the intestines of animals. It has a rod shape and is about 2 micrometers long. It reproduces through binary fission and has all the characteristics of living things, such as growth, response to stimuli, and cellular organization, despite being a single-celled organism without a nucleus. E. coli was first identified in 1885 and provides vitamins to its animal hosts while living in their intestines.

2. Characteristics of All Living Things
S 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. Shapes
S 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. Escherichia Coli
S 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. Response
S E Coli responds to a sudden increase in temperature by
overproducing a protein the posses.

6. Reproduction
S E Coli, like many other bacteria, uses binary fission to
reproduce. This is how binary fission works.

7. Growth
S This reproductive cycle from the page before shows the
growth of cells like E Coli as well as their reproduction.

8. Organization
S 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. 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.
