why is bacteria in two different kingdoms?
553651
u must be knowing that all organisms are classified into five kingdoms-monera,protista,anemalia,fungi and alge.\n\nthe MONERA phlum[group] consists of bacteria which are prokaryotic in nature -i.e, the cell doesnot have membrane bound organneles or nucleus.\n\nthe Protista group consists of organisms that are eukaryotic in nature-that is they have well defined organneles.\nthis is one reason that bacteria is kept in two separate groups.

Prokaryotic cells do not have the same lifespans as eukaryotic cells. This is because they do not carry out the same metabolic functions as eukaryotic cells.

There are more described species of insects at present, but it's unlikely that this is representative of the actual diversity of the organisms.\n\nInsects are easier to distinguish using visible characters, and there's more economic impact of various insect species, so there's more incentive to work on them.  \n\nWhile there may be millions of different species of bacteria, they are harder to distinguish from each other, except possibly by comparing genetic material.  So no one has actually done the work necessary to categorize all of those species yet.

Unlike bacteria that multiply in the correct conditions of their own volition, viruses have to invade a cell and change it to spread.  They can't just be, they have to take something over.

No, plantkon are just very small plants and animals. They are not single celled organisms, but if they were, that wouldnt automatically make them bacteria. Bacteria can only be prokaryotic organisms.\n\nBacteria are constantly being eaten. There is bacteria on everything you eat, and very often, bacteria is used in the production of food.

1. Kingdom Monera [10,000 species]: Unicellular and colonial--including the true bacteria (eubacteria) and cyanobacteria (blue-green algae).\n\n2. Kingdom Protista (Protoctista) [250,000 species]: Unicellular protozoans and unicellular & multicellular (macroscopic) algae with 9 + 2 cilia and flagella (called undulipodia).\n\n3. Kingdom Fungi [100,000 species]: Haploid and dikaryotic (binucleate) cells, multicellular, generally heterotrophic, without cilia and eukaryotic (9 + 2) flagella (undulipodia).\n\n4. Kingdom Plantae [250,000 species]: Haplo-diploid life cycles, mostly autotrophic, retaining embryo within female sex organ on parent plant.\n\n5. Kingdom Animalia [1,000,000 species]: Multicellular animals, without cell walls and without photosynthetic pigments, forming diploid blastula.\n\n\nSo far those are the five Kingdoms I know of if there are a few more I have no idea but it is possible. Or you are confusing with bilogical organizations, which are 7

Each of the microbes performs a limited number of tasks (so to speak) in maintaining soil structure; some of the tasks are, I suspect, mutually exclusive of others...\n\nIt is actually impossible to be sure why there are so many diverse organisms, beyond that: we weren't there when the structure was put together, and the best we can do besides make this humble observation is make scientific, wild-eyed guesses based on whatever theory we prefer...

Some bacteria move about their environment by means of long, whip-like structures called flagella. They rotate their flagella like tiny outboard motors to propel themselves through liquid environments. They may also reverse the direction in which their flagella rotate so that they tumble about in one place.

Humans do not dominate anything. Bacteria are way more successful than us at surviving, reproducing, colonizing and transforming every tiny corner of Earth's surface, air and water. The Earth contain more bacteria than all other organisms combined. They also fill ourselves: did you know that our bodies host more than 200 species of bacteria and that we couldn't even survive without them?

Defining a species of virus is problematic because many biologists do not consider them to be alive.  It's the "organism" part of the species definition (any species definiton) that's a problem.\n\nDefining a species of bacteria under the biological species concept is problematic because the BSC defines a species as a collection of organisms that can reproduce only with other members of the same species.  Bacteria reproduce asexually, so they're not reproducing WITH anyone.  However, there are other problems with the BSC. For example, lions and tigers are clearly separate species, but they can interbreed.  So biologists tend to favor other species definitions (like the morphological species concept), which can effectively classify lions and tigers (as well as several other species that are able to interbreed).  These species definitions have no trouble classifying bacteria.

they are evolutionary distinct!\narchae dont have a peptidoglycan cell wall.\nmoreover they live in extreme conditions such as high temp springs and very low pH!

Bacteria have very short life cycles so adapt very quickly and many species do live in the artic. Like any process in coll temperatures the activity is decreases due to a decrease in kinetic energy, so activity is low.

Yeast cells are not bacteria.\nThey are unicellular fungi. The cells multiply asexually by mitosis - a process called budding. This description is used because the daughter cell appears as a small 'bud' from the original cell before separation.\n\nFor more information look here:

Uhhh.... isn't bacteria a single-cell organism?\nPlease be more specific.
