Bacteria+-+GG

= Introduction = toc Imagine your just outside having a glass of water, just relaxing. Breathing in and out… little did you know, you are surround by a cell. A cell that is harmful yet helpful is surrounding you. That cell is Bacteria! It’s in your water, In the air you're breathing, on the ground around you, in your food, it’s even in you. The bacteria cell is strong with all the layers it has. Don’t be worried about this because not all bacteria will hurt you or the things around you, but it will help you and the things around you.

**How can Bacteria Be Helpful?**

People may think bacteria is only harmful,but, it actually is helpful. According to World Book Online in the article __Bacteria__, it lives in our body and gives us the vitamins we need. If bacteria didn’t give vitamins, then we wouldn’t be healthy. This shows how bacteria makes us healthy. Bacteria doesn’t just keep us healthy from the vitamins we need, but it helps us with digestion. Our digestive system needs bacteria to help us digest. Even in the article it says " These bacteria help in digestion and in destroying harmful organisms. Intestinal bacteria also produce some vitamins needed by the body." Another way bacteria keeps us healthy is by helping our immune system. The bacteria cell fights harmful organisms that attack your body. Bacteria is helpful by making the human body healthy.

= How Can Bacteria Be Harmful? =

Not only are there helpful bacteria cells, but harmful bacteria. Harmful bacteria makes the body unhealthy by giving the body diseases. Some of these diseases include Cholera, Gonorrhea, Leprosy (a.k.a Hansen’s disease), pneumonia, Syphilis, Tuberculosis, Typhoid fever, and a Whooping cough. Another type of bacteria,that is harmful, can produce toxins. Toxins are poisons that cause diseases. These diseases include diphtheria, scarlet fever, and tetanus. In the article "Bacteria" on World Book Online it explains how the bacteria gets in the body, " The bacteria enter a human body through its natural openings, such as the nose or mouth, or through breaks in the skin." Now, we know harmful bacteria can give you diseases, but they also destroy healthy cells in a human being. When the bacteria attacks the healthy cells in a body, it prevents the human from properly functioning. media type="youtube" key="kxM_9DL2GYw" width="419" height="238" Click on this link to learn more about why bacteria is harmful and why it is helpful.

= = = Structure of Bacteria Cell =

Bacteria is not only one shape, it can actually be three different shapes. Even if they are different shapes they are all very,very small. One shape is called Spherical: Bacteria in the shape of spheres,form a chain of cells, looks like a row of circles. As you see in the picture below, this was an close on a bacteria cell. Now, for the inside of a bacteria cell there are a lot of layers. The first thing you see on a bacteria cell are the pili and fimbrae. The pili and fimbrae lets the bacteria cell attach to other cells or surfaces. You can also call the Pili and Fimbrae the bridges. The second layer of the bacteria cell is called the capsule (soldier). This layer protects the bacteria from being harmed from anything. The third layer of the bacteria cell called the Cell Wall (scaffolding). The cell wall keeps the bacteria’s shape the same. Except, molecules can enter or leave the cell unlike plant cell walls. The fourth layer is called the Plasma Membrane (doorman). This is one of the outer layers of the bacteria cell. It controls what nutrients, ions, and waste leave and enter the cell. The fifth layer of the bacteria cell is called the Cytoplasm (where the action happens). This is a fluid that fills. The fluid contains internal pressure. It also has organelles suspended into it. The Ribosomes isn’t a layer but it is what comes next in the bacteria cell. Ribosomes create the proteins the cell needs. Finally, the Nucleoid (the mayor) is the last part of the bacteria cell. The Nucleoid contains all D.N.A. The Nucleoid is made from bacteria D.N.A gathered into clumps, and moved to the center of the cell. Also, on the bacteria cell there is something called the Flagellum. The Flagellum helps the bacteria cell move. The bacteria cell can have one or more of the Flagellum. If you want to see an example of what the bacteria cell looks like you can go on the link above the diagram.

= Where Does Bacteria Live? = Bacteria can live multiple places. One place bacteria is found is on every earth habitat. According to Microbiology Online, It is found in oceans, rock, soil, and even arctic snow. Another place bacteria can live is in (or on) organisms. These organisms include plants, animals, and humans. In the human body, there are 10 times as many bacteria cells. Bacteria also lives in lakes and under sheets of ice. This cell is everywhere. Bacteria is in the air and in your water. It can be found almost everywhere.

= Conclusion =

Bacteria has a love-hate relationship in your body. It helps your digestive system and immune system be as healthy as it can be. But, it can also give you many diseases, and make your body unhealthy. Bacteria can make you sick in one second. You may just take one breath of oxygen, and get sick from the bacteria that was floating in it. Bacteria was the first thing that has lived on earth. It has been in everyone's body making new diseases that doctors/scientists have to cure. As scientists/doctors fight bacteria, bacteria fights back.
