Bacteria+-+CP

=Introduction= toc Drinking, eating, breathing, shaking hands with someone, putting things in your mouth. These are all ways to spread, scary, vicious, disease causing bacteria. Some have creepy, wiggly arms called flagella, some are the shapes of spirals or spheres or just look like a tangled up piece of string. Bacteria can cause Strep Throat, Food Poisoning, Tuberculosis, E-coli, Salmonella, and more. Although you probably don’t know half of those bacteria caused diseases, it still sounds scary of how many diseases they can spread. But not all bacteria are bad...

=__Function: What is the Function of Bacteria?__= Bacteria can come in many shapes and sizes. Bacteria have many different jobs to do, and they are single celled organisms that can do many different things. A simple thing they can do is move around with their flagella, a tail or whip on the bacteria that whips around so the bacteria can move. Bacteria also have pili and fimbrae. They are like arms to a bacteria to help them grab onto different surfaces, even another cell to attack it. Bacteria in your digestive system break down molecules that you body can’t digest, cow's need these bacteria in their body or else they would not be able to eat grass. Although, lots of bacteria are good for us, other types can cause diseases and sicknesses. These bacteria can cause food poisoning, strep throat, tuberculosis, and way more. Pathogenic bacteria can cause diseases by releasing chemicals called toxins that are either specified as endotoxins or exotoxins. Endotoxins store toxic substances that they produce and is stored in the cell wall ready to be released when the wall breaks. On the other hand, exotoxins excrete (separate and remove as waste) toxic proteins. Exotoxins also produce systemic, potent effects and is usually sensitive to heat. Bacteria come in many different forms, there are countless amounts of bacteria in the world, and countless amounts of different jobs each one has.

=__Structure: What do Bacteria Look Like and How Does That Affect The Things They Can Do?__= Although bacteria usually come in shapes of rods, spheres, and spirals, they can be in shapes that you’ve never seen in your life! It seems that bacteria are just tiny single cell dots under a microscope but have interesting attributes inside and out. On the outside of the bacteria there is sometimes a flagella, possibly multiple, and the pili and fimbrae to attach on to different surfaces. Inside the bacteria is a nucleoid and ribosomes that make proteins. Sometimes you can find prokaryotic cells, their nuclear material is not surrounded by membrane.

=__Real World Connection: Where Are Bacteria Found and how do they get there?__= You take a shower and use your best soap, scrubbing as hard as you can. You are safe from bacteria, or are you... the truth is, you are not! Although taking showers does eliminate lots of bacteria, it’s still scary to think, but bacteria is still there. Bacteria is EVERYWHERE, according to BrainPop,Bacteria, there are about five nonillion, which looks like this: 5000000000000000000000000000000. It’s five followed by THIRTY zeroes, and “there are more bacteria inside your digestive tract then there are humans that have ever lived.”-Tim. Another scary but true fact is that the average adult human is made of around 10 trillion cells, and carry about 100 trillion microbes (micro organisms, usually bacterium that cause diseases) Where are bacteria found and how do they get there? Bacteria are found in our water, food, and even in our bodies. So yes, bacteria is literally everywhere. When you drink some water, eat a snack, or just breath, there are bacteria travelling into your body. That’s why your parents always say, “Did you wash your hands?” after you use the bathroom, because bacteria can spread so easily.

=__Conclusion__= There are many different kinds of bacteria and all around you that look very different and have different purposes. Yes, they can cause diseases and sicknesses, but they can help some parts of your body. Bacteria are not cells that can be found in only certain places like animals or plants, they are everywhere. Bacteria surrounds us and they always will so why not learn a little bit about them.
