Bacteria+-+BS

=Introduction= toc

Bacteria can reproduce really quickly; Once every 20 minutes. This can cause a cold to become contagious. In most cases bacteria can be destroyed by white blood cells and antibiotics. However, if it turns into a superbug your sickness could be deadly. But not all bacteria are bad. They can also help you. For example bacteria can help your digestive system by breaking down waste.

=Good vs. Bad=

Some bacteria is good and some bacteria is bad. One example of how bacteria is good is that they help clean up wastes and dead animals or plants. Other bacteria that is found in soil helps plants grow. Did you know that people and animals have bacteria in their intestines? That bacteria is good because it helps people and animals digest their food. (“Harmful and Helpful”)

=Reproduction=

Bacteria can reproduce once every 20 minutes. (“Bacteria”) Bacteria reproduce through fission. That is when it produces two cells with the same genetic material as the parent. Other bacteria reproduce by exchanging genetic material through a thin tube. This process is called conjugation. (Padilla et al 52) Some other bacteria reproduce through a small, round, thick-walled resting cell called endospore. (Padilla et al 53)

=Structures of a Bacteria=

A bacteria cell is much smaller than a plant or animal cell, but it has some special parts that help it survive. The first part is the flagellum. It is a round tube shaped like thing that helps the bacteria move around freely. (Padilla et all 24) The second part is the pilli. The pilli helps the bacteria attach to other bacteria cell. The third part is the capsule. The capsule helps the bacteria by protecting it. The fourth part is the storage granules. The storage granules stores the cell’s energy.

=SuperBugs=

In most cases bacteria is defeated by white blood cells or antibiotics. But there are some that can’t be defeated so easily which are called the SuperBugs. SuperBugs are caused when antibiotics are no longer working against the bacteria that is causing the sickness. Example: Antibiotics resistance results when some bacteria are able to survive after being exposed to antibiotics and they reproduce more so the sickness still continues. The recent increase in tuberculosis cases demonstrate the impact of antibiotic resistance as patients began to take antibiotics to treat tuberculosis in the 1940s, the number of tuberculosis cases dropped significantly. Unfortunately, there were always a few tuberculosis bacteria were resistant to the antibiotics. As resistant bacteria survive and reproduce, the of resistant bacteria increases. The number of tuberculosis cases has increased over the last 20 years. (Padilla et all 63)

=Conclusion=

Don’t underestimate bacteria by its size .It has positive and negative functions. Bacteria can help your digestive system by breaking down waste. On the other hand it can cause illnesses but that is not a problem as long as you take in antibiotics. there is a problem, if you take too many antibiotics the bacteria is going to start resisting and it turns out to be a superbug which can cause deadly sicknesses.
