Transcript of . Bacteria are single-celled organisms cells that can act li
Bacteria are single-celled organisms cells that can act like plants or animals. They are some of the oldest and most diverse forms of life.
Scientists classify bacteria into three shapes, sphere, spiral or rod .
Your body is full of bacteria, there are actually more bacteria cells in your body than there are human cells. There are more bacteria in your intestine then there are people on earth. Don;t work they are usually friendly and actually help us in lots of ways
Humans have used bacteria to help us in other ways for thousand of years. Bacteria is used to make yogurt and cheese. The flavor of these foods comes from bacterial by products, not exactly bacteria poop but close. Tasty, tasty bacteria poop
Bacteria can produce oxygen for us to breathe – some Scientist estimate I could be as much as half of the oxygen we breathe so next time you see a bacteria in need help out they are helping you
Bacteria can cause food poisoning – But dangerous bacteria is killed when we cook food and grows very slowly in the cold so that is why it is important to properly cook and refrigerate food. I mean if you don’t like being violently ill and dieing it is important but if you like that kind of thing, to each his own
Bacteria and fungus are often in close proximity and they sometimes compete for resources or try and eat each other. For that reason many of our antibiotics are derived from the natural defenses of fungi against bacteria.
Some bacteria live on the inside of animals like cows. These bacteria allow cows (and other animals that eat grass) to digest the material the grass is made of, called cellulose. Humans don't have the right bacteria, and so we can't eat grass!
Bacteria that enter human bodies that don't belong there invade human cells, stealing nutrients and releasing poisons. These bacteria can make people sick, can cause skin infections, and are generally very bad for people.
