Bacteria+-+DW

= Introduction = toc A bacteria cell can reproduce into two in twenty minutes then into four twenty minutes later. Structures like flagella which help the cell move and help with it function. Illnesses come from these structures like people can get lyme disease or food poisoning because of bacteria. Bacteria makes people sick and balance out the immune system at the same time. Bacteria has been around for at least 3.5 billion years ago, making them the oldest known life-form on the planet.

= How Do Bacteria Reproduce? =

Bacteria spread and reproduce so much that there are 5,000,000,000,000,000,000,000,000,000,000 (5 nonillion)bacteria around the world! Living cells, including bacteria, must be able to reproduce themselves. Bacteria do this by a simple process in which one cell increases in size and then divides into two equal cells. This form of asexual reproduction is called binary fission. Instructions for copying itself are contained in the genes. The cell also contains the basic chemicals, cell machinery, and energy needed to complete the manufacturing process. With abundant nutrients, bacteria will grow and reproduce very quickly. Some bacteria can divide every 20 minutes, if conditions are right. That means that a starting bacteria could multiply into a million bacteria in less than 7 hours(“Grolier”). Fortunately, the Earth will not be overgrown by bacteria because inadequate food supplies and harmful conditions keep them in control. (“Grolier”)

= What Structures Do Bacteria Have that Helps With its Functions? =

Flagella helps a cell to move, a cell can have many, one, or none. Most that do not have a flagella cannot move on their own. Ribosomes contain the instructions for all of the cell’s functions. (From Bacteria To Plants). Chromosome: the bacterial chromosome has full capability to replicate itself. Cell wall: protects the bacteria cell from bad things. (Invisible Intruders). Flagella is like wheels because they help things to move. Another thing is how ribosomes are like a box of Lego’s because they have instructions to it all. Also, chromosome is like a 3D printer because it can replicate itself into a new one. Finally, the cell wall is like a brick wall because it doesn’t let anything through.

= What Illnesses Come From Bacteria? =

There are lots of illnesses you can get from bacteria but I can only name some of them. Some of them include, strep throat, food poisoning, tuberculosis, bloody urine, painful and/or frequent urination, diarrhea, flu-like symptoms (fatigue, fever, sore throat, headache, cough, aches and pains), nausea and vomiting, pain such as joint, ear or abdominal pain, weakness, tooth and gum disease. These diseases or illnesses have a prevention and symptoms like lyme disease a prevention is to tuck pants into socks and wear a long-sleeved shirt. A symptom is a rash at site of tick bite; chills; fever; body aches; joint swelling. Food poisoning a prevention is to properly cook and store foods; avoid foods in rusted and swollen cans. A symptom is vomiting; cramps; diarrhea; fever. Lyme disease is an inflammatory disease characterized at first by a rash, headache, fever, and chills, and later by possible arthritis and neurological and cardiac disorders, caused by bacteria that are transmitted by ticks. Food poisoning is an illness caused by bacteria or other toxins in food, typically with vomiting and diarrhea. [|__https://youtu.be/ICWLF9lccNk__]

= Conclusion = Bacteria have been around for at least 3.5 billion years, making them the oldest known life-form on the planet. Most bacteria have yet to be identified. In 2003 geneticist [|J. Craig Venter] began [|trolling the high seas] and analyzing the water. On his first trip he fished out more than a million never-before-seen bacterial genes. Your body has 10 times more bacterial cells than human cells. Bacteria have even set up permanent camp inside our cells. Mitochondria, the power­houses that supply energy to nearly every cell in the body, are the descendants of [|bacteria that were engulfed by larger microorganisms] billions of years ago.
