Everyone knows what bacteria is. Most people think it's something that's out to kill us. But people don't know what bacteria really does for us. Bacteria is something humans need to live. Without it we would be all dead. In that matter nothing would be alive without bacteria. No living organism could exist without bacteria.

Structure
Bacteria is everywhere around us. It surrounds us. Although we can not see it normally it’s there. Some people may know bacteria as germs. Bacteria is a thing that is micro size like cells and viruses. one of it’s shapes are like a pill that has hair and a tail growing out of it. Those are called flagella. The flagella help the bacteria move the hairs control the movement and the tail propels it around.Like how a tadpole propels itself around with it’s tail like thing.

Autonomy
Bacteria’s main structure is kinda a mix of plant

and animal cells. It has a cell wall like a plant cell but it's shaped like an animal cell and has the components of one inside of it.(Look at the diagram) The cell wall it has protects it from anything trying to enter the bacteria. The cytoplasm in the bacteria is a gel like thing that has organelles in it. The Nuclead is the main control point for the bacteria. It controls everything that the bacteria does. The capsule is the outside layer of the bacteria cell. It’s like skin.

Bacteria isn’t just a killer it’s also one of the main reasons why the human body works like it does. It’s also how we make some foods.

Bacteria is in every human's body it helps us digest food, helps us breath, and helps out with some of our organs functions. We also use bacteria to find cure to harmful diseases by analyzing bacteria scientist can learn how to fight an illness or many illnesses. Another thing Helpful it does is it makes certain types of food. Like, cheese, bread, and yogurt. Imagine a world without any of those things.

Without Bacteria many things wouldn’t be possible. Including life itself. Bacteria is the reason why almost living organisms exist. All animals and humans evolved up from bacteria. Bacterias collide and eventually mixed and started to evolve. So pretty much without bacteria no animal or human could exist.

Harmful Bacteria

Although bacteria is how all animals and humans exist they are also bad in many ways. For instance bacteria causes lots of illnesses. Such as cholera, gonorrhea, leprosy (Hansen's disease), pneumonia, syphilis, tuberculosis, typhoid fever, and whooping cough. Those are only some of the illnesses that bacteria causes. Since bacteria travels in air,our food and our water. It also has an easy way of getting into of our body from natural openings. like our mouth,nose,eyes and through breaks in the skin. And since bacteria travels in air,our food and our water. Some bacteria that normally help out in our bodies can sometimes cause infections when bad bacteria mixes with them. Infections are really deadly and can kill. So bad bacteria is almost impossible to avoid. So thats a real problems for us humans.

Conclusion

Bacteria is a incredibly fascinating subject. They take on various forms and are both harmful and helpful in many ways. As humans we should research more about it.
