what makes bacteria differ from all other living organisms?
917660
they have no nucleus, no membrane-bound organelles, their ribosomes are different (smaller), they have circular DNA, and they are much smaller.

Bacteria, if thats what you meant, isn't made. It is a life form that grows. Bacteria can be grown on a nutrient agar culture in a petri dish. Or, just leave some bread or an old peice of fruit out and you'll get all sorts of bacteria. By the way, there is bacteria all over your body right now.

A viruses is a small structure that has a protein coat with a pieces of genetic material.  It invades the cell of its host and uses the hosts DNA to replicate its own genetic material.  Once the cell has replicated the viruses DNA the cell ruptures and the viral DNA is sent throughout the hosts body.  A virus is not technically classified as a living thing.  It is not able to replicate and reproduce with out a host.\nA bacteria is classified as a living thing.  It is a prokaryotic organism with the ability to reproduce using its own genetic material  DNA/ RNA.

Prokaryotes ie; bacteria

E.\nBecause bacteria can obtain nutrition chemically, they can live in conditions that no-one thought possible, for example in volcanic vents at the bottom of the ocean.

Bacteria do have fixed size and shape.\nSize varies from 0.5 to 50 microns, generally 1 to 5 X 0.5 - 1 Micron. ( 1 micron = a millionth part of a milimeter )\nShape is variation of two basic shapes - spherical i.e. Cocci (singular Coccus ) and cylindrical i.e. rods or Bacillus. All other forms are variations of these two. \nCocci in pairs - Diplococcus\nCocci in cains - Streptococcus\nCocci in clusters - Staphylococcus\nCocci in tetrads - Gaffkia\nCocci in cubes - Sarcina\nRods - Bacillus\nCurved rods - comma shaped - Vibrios\nSpirals - Spirrilum, Spirochaetes\nFilamentous - Actinomycetes\nRods wth tapering ends - Fusobacterium\nRods with bifercated ends - Bifidobaterium\nCells without cell wall do not have fixed shape, these are Mycoplasma.\nYou will get this information in any basic microbiology book or in wikipedia

think of it as a bacteria...bacteria is a living organism...if you disinfect it will it not die?does bacteria think?does bacteria feel pain and what not?\n\nveggies live off water/sun/nutrients just as we do.veggies begin to rot bebore dead/wasted.\nhumans rot after death...\n\nwhat will you do?\nwhat will you think?

Bacteria are procaryotes. Their cell structure is different from those of plants and animals (Eucaryotes) they are in their own category altogether. Years and years ago they were categorized as plants. Some of them have clorophyll. How old is your brother's science book?

Most of the bacteria that can be cultured represent only a tiny fraction of what's out there. Bacteria exist in practically every niche observable but in general, the best way to cultivate bacteria is to simulate their natural environment. That's why many infectious bacteria are grown on agar (a sugar similar to the ones found in our body) and incubated at 37 degrees celsius (the temperature of the human body)

bacteria, viruses, cyanobacteria or fungi?  or do you mean specific examples

bacteria are prokaryotic(no nucleus)

Bacteriology strictly is the study of bacteria.  Microbiology is the study of all organisms that are not generally visible by the naked eye.  Microbiology includes bacteria, archaea, certain algae/protists, and some fungi.  Microbiology also includes the field of Virology, the study of viruses, which are not considered to be organisms.

That is a very cool question. Biology is the study of life. Not just squids and kangaroos but you and the foods you eat.\n\nHey I love food, and air and water, without them none of us would be here! They are essential.\n\nBiology helps us understand where our essentials come from. For instance, a small change in an ecosystem could radically effect farmer's ability to grow plants and raise animals we depend on to live. In the 1930's the Dustbowl wiped out farms across a wide area!\n\nAlso many plants and animals produce complex chemicals which we use in everyday medicine. Aspirin for instance is derived from the willow tree. Antibiotics like Penicillin were discovered in spores of mold.

We actually can not give a chart of living organisms and non living organisms but we can differentiate them by giving differences and similarities.\nLiving                       No living\nThey can reproduce while noliving can not reproduce \ncan locomote    while noliving can not locomote\ncan feed       while noliving can not feed\ncan respond (irritability) while noliving can not respond to stimuli\ncan excrete wastes while noliving can not excrete wastes\ncan respire while noliving can not respire

In my own observation, all micro organisms puzzle the modern biologists, especially the inexplicable origin of the life force behind the protoplasm in the living nucleus.  All that they have done so far is to name and describe the composition (oxygen, hydrogen, carbon, nitrogen, calcium, magnesium, sulfur, potassium, etc.) and the observable phenomena surrounding the cell.  \n\nOn the othe hand, it is also possible that biologists understand this already, they are just trying to find the right time and the right words to make us understand.  As the saying goes: "The teacher will appear when the student is ready."

viruses cause viral infections, and bacteria cause bacterial infections. But they're also different in other ways.\n\nViruses are much smaller than bacteria.\n\nViruses are not living organism so they need a host.

Bacteria is a "group noun" (like a flock) for a single type of bacteria. For example "300 e. coli bacteria." (similar to 300 in the flock (flock is singular))\n\nBut when referring to different types of bacteria the noun is typically plural. For example "the the surface of human skin is infested with many bacterias, some harmful, some harmless."  (similar to "the many flocks that we saw flying south for the winter")
