why there is flagella in bacteria?

for mobility of some bacterias that make it swim,glide or axial move or swarm. some have one flagella(monotrish)some few(lofo....)some on the polars(amphi..)and some all around them(peri...)

Hi there, \n\nMany types of bacteria undergo cell division by a procedure called 'Binary Fission'\nYeast does not undergo cell division, however, it reproduces through 'Budding'\n\nHope this helps. If not, I'd be glad to assist you further. Bye!!\n\nrule wid style n luv@vinny

eukarotic bacteria are unicellular; fungi can be multicellular whereas bacteria can not. Bacteria move themselves by means of a flagella unlike fungi which don't. Bacteria lack a nucleous and mitochondria unlike fungi. Many bacteria have differing cell walls from fungi. I believe the term used is peptidoglcoans, which describes the cell wall.

Its to fdo with the type of enviroment the bacterium is living in. Those that live in wet enviroments, eg in water or in your GI tract will have a method of motility in order to move around to obtain nutrients. Conversely those that live on bread for example, have their nutrients right there and so dont need to be motile. Of course, having said that, bacteria that are obligate intracellular parasites dont as far as im aware have flagella so there is probably something else involved there. Maybe its the spreading of its progeny.

If by morphology you mean "Gram-negative rod" then you'd get false positives.  All enterobacteriaceae are Gram-negative rods, but not all Gram-negative rods are enterobacteriaceae.\n\nColony morphology won't necessarily help a lot, either, as I don't think that there is a consistant enteric colony shape.

Bacteria, one-celled organisms visible only through a microscope. Bacteria live all around us and within us. The air is filled with bacteria, and they have even entered outer space in spacecraft. Bacteria live in the deepest parts of the ocean and deep within Earth. They are in the soil, in our food, and on plants and animals. Even our bodies are home to many different kinds of bacteria. Our lives are closely intertwined with theirs, and the health of our planet depends very much on their activities.\n\nMuch of our experience with bacteria involves disease. Although some bacteria do cause disease, many kinds of bacteria live on or in the human body and prevent disease. Bacteria associated with the human body outnumber body cells by ten to one. In addition, bacteria play important roles in the environment and in industry.\n\nWe have all had bacterial diseases. Bacteria cause many cases of gastroenteritis, sometimes called stomach flu. Perhaps the most common bacterial disease is tooth decay. Dental plaque, the sticky film on our teeth, consists primarily of masses of bacteria. These bacteria ferment (break down) the sugar we eat to produce acids, which over time can dissolve the enamel of the teeth and create cavities (holes) in the teeth.\n\nTooth decay provides a good example of how multiple factors contribute to bacterial disease. The human body hosts the bacteria, the diet supplies the sugars, and the bacteria produce the acid that damages the teeth.\n\nCommunities of bacteria form what are called biofilms on many body surfaces. Dental plaque is a biofilm covering the teeth. Biofilms also cover the soft tissues of our mouths and the inner surfaces of our nose, sinuses, throat, stomach, and intestines. Even the skin has bacterial communities that extend into hair follicles. Bacterial communities differ in each region of the body, reflecting the environmental conditions in their specific region. Bacteria that inhabit the surface of the stomach, for example, must deal with extremely strong acid in the digestive juices.\n\nSome regions in the interior of the body are sterile—that is, devoid of living organisms other than the cells of the body. Sterile regions include the muscles, the blood, and the nervous system. However, even these regions face constant invasion by bacteria. The body’s immune system is designed to rid the body of these invaders.\n\nA healthy, balanced community of bacteria is extremely important for our health. Some of these organisms protect us from disease-causing organisms that would otherwise infect us. Animals raised in a completely germ-free environment, without any contact with bacteria, are highly susceptible to infectious diseases if they are exposed to the outside world. Bacteria in our bodies also provide us with needed nutrients, such as vitamin K, which the body itself cannot make. The communities of bacteria and other organisms that inhabit the body are sometimes called the normal microflora or microbiota.\n\nFor the rest of this information, go to:)\n\nhttp://encarta.msn.com/encyclopedia_761574409/Bacteria.html

In general, organisms with less complexity, are less likely to have homeoboxes\n\nHomeoboxes seem to be reserved for higher eukaryotic cells (like human cells) that require specialized cells which will coordinate complex tasks in conjunction with other specialized cells (at least that's my simplistic viewpoint).\n\nE.coli, for example, does not contain homeoboxes because it is not dependent so much on its sister cells. \n\nI had fun thinking about the answer to your question.  Don't forget to pass on the good karma.

Bacteria are one celled organisms. They come in 3 shapes. Rods, spheres and spirals. Some have means of transportation like flagella and cilia. Bacteria can be helpful such as in cheese making or pathogens causing disease. others are helpful in decomposing or in helping plants in the nitrogen cycle.

Bacteria are not at all similar to cellular organisms.\n\nThey have no tissue or organs, since those are composed of cells.\n\nBacteria are much smaller and simpler than cells, although their DNA is surprisingly complex.\n\nBacteria are actually quite fascinating and they have many interesting facets that are not found at all in cellular organisms.  The flagellum, for example, in some varieties is powered by a tiny microscopic motor that is powered by acid.\n\nThe world of bacteria is only now beginning to be opened up through the relatively young science of microbiology.  I would encourage to read more about them if you think you would find it interesting.\n\nAfter seeing the other comments, I felt compelled to add that bacteria are NOT cells.

Bacteria have very few chromosomes compared to us, so there must be a very simple bacteria with only 1 chromosome.  Their chromosomes are circular and are called plasmids.

Well, at the least conjugative plasmids are known to occasionally integrate into bacterial chromosomes. I think some others are, but if I had to pick just one, that would be it.

It is a prokaryote because:\n\na. It contains a nucleiod instead of a nucleus\nb. It has a single chromosome (one DNA)\nc. It lacks a nuclear membrane\nd. Mitochondria is absent\ne. It divides by binary fission, not by mitosis.\n\nAlso, Staph. Aureus is a bacterium and all bacteria are prokaryotes.\n\nHope this helped.

I would think that in a liquid medium the bacterium would like to help retain form/shape,because that what a pellicle is a a thin layer supporting the cell embrane. so if a bacterium in a liquid medium not evolved an effective way to continue surviving thus thriving in its environment it might just cease to exist an evolutionary dead-end.

It is the wavelenghth that is most predominant in bacteria (though this is an overstatement because bacteria is composed of many molecules that exbit differnt wavelenghths) but this is to determin the absorbance so you can use it later as a standard for how many bacterial cells are in a certain fluid.

Why is this in Biology?

the bacterial flagella is a well studied model used to display the evolution of proteins. For example, there are great similarities between some of the flagellar proteins and those of prokaryotic thype III secretion systems. Proteins that change function over time are generally discovered by different people in different models and thus provided different names.
