where do flagella live?

Flagella are not alive.  That's like saying that my spaghetti sauce lives in my pantry.  Flagella are bundles of proteins that extend out of single celled organisms and are used by those organisms for motion.\n\nCertain species of bacteria and protoza, as well as animal sperm cells, have one flagellum (or many flagella)

They can also be found in most tropical fish stores. The snails are usually unwanted hitch-hikers on aquatic plants.

Cuttlefish don't have any air-holes on the inner surface of their tentacles.  Or anywhere else for that matter.\n\nCuttlefish are strictly marine, and don't really have much interaction with air at all.  They breathe water, live in water, breed in water and feed in water.\n\nPerhaps you are refering to the suction cups on the tentacles?  The inner surface of the tentacles has a number of suction cups used in grabbing prey or other items.  The number of suction cups varies depending on the species of cuttlefish, and their age/size, and probably individual variations as well.  \n\nSo the answer would be somewhere between some and lots.

The protist needs to maintain homeostasis, the balance in the body, in order to live. Diffusion and Osmosis acheive this by allowing nutrientrs to come in and wastes to leave.

There are several protozoans that participate in mutualistic symbiosis with animals, they mostly reside in the gut. For example, termites would not be able to digest wood if protozoans did not live in their gut. As a matter of fact, 33-50% of a termite's biomass is protozoans or bacteria. \nCorals are highly dependent on their photosythetic symbionts (dinoflagellates).\n\nyou can read more examples at http://azolla.fc.ul.pt/aulas/Estagios/Docs/MutualisticSymbioses.pdf#search='protozoan%20mutualistic%20symbiosis' \njust scroll down to the section on protozoans.\nmore info at http://www.101science.com/Symbiosis.htm\nhope this helps!

It depends whether you are talking about organisms that are single cells, or cells that exist in eukaryotic tissues.\n\nThe problem with finding the smallest cells is that they will undoubtedly turn out to be the smallest bacteria... these organisms are likely to exist only in places that are very difficult to reach, because extremely small size is in fact an adaptation to a (typically harsh) environment: reduction in size maximises surface area in proportion to volume.  When life gets very tough, having a maximal surface area is important, because in general, important life processes occur through cell walls and surface membranes.\n\nSome hyperthermophilic archaea (archae-bacteria that colonise hot volcanic and deep subterranean environments) are rod-shaped organisms 0.17 microns in diameter (genus Thermofilium), disk-shaped organisms 0.2-0.3 microns in diameter, 0.08-0.1 thick (genera Thermodiscus & Pyrodictium).\n\nCells in the human body are typically 5-20 microns thick.  I think Bacteria_Boy could be right about the nerve cell.\n\nIndividuals of the genus Acetabularia, a protist (single-celled) marine green alga, are composed of clearly differentiated parts (eg: foot, stalk, head), but grow up to about 5 cm in height.  These are the largest single-celled organisms that I know of.

only sperm cell has flagellum.the sperm cell and egg cell r haploid in condition and r produced by the process called meiosis or reduction division

Those answsers are wrong. It is a bacteria that lives on an aphid. Here is the link to prove it:\n\nhttp://phylogenomics.blogspot.com/2006/10/worlds-smallest-genome-of-cellular.html

usually at the centre. but sometimes lies in the periphal region if vacuole is too large(vacuole displaces the nucleus eg. in plant cell) \n    its size differs from cell to cell. however  its size is significantly larger than many other cell organelles like ribosome,lysosome, ER, etc but smaller than vacuole in plant cells

it's located in the cytoplasm

Some algae are motile. Single-celled algae often have flagellae and move in a spiralling manner. Others do not have flagellae but secrete a sticky substance which attach them to the substrate, enabling them to glide along leaving a trail of slime behind.\n\nSome Diatoms (pythoplankton) can also move on their own thanks to their flagellae.  Then there's the rhodophyta and the cyanobacteria, which are not exactly plants but will also enlighten your way to finding what you need.\n\nOtherwise, plant cells are not moile.

Maybe prokaryotes. But I'm not sure... I think there's still a debate about them cause they're not really living creatures... They are "alive" when they are inside a host, but otherwise, they're just lifeless proteins.. :)

They are Flagellates, meaning they have a large flagellum or whiplike cilium at one end, which propels them around. So yes, they are motile.

They are all prokaryotes, some may have a thick cell wall made of peptodiglycan.  They can live in extremely acidic, basic, hot, cold, salty, or wet environments.

...to live and reproduce? You need to be more specific... what kind of animal cell? In what organ? Or is it a single-celled organism? Do you mean the structure?

Seashells don't "live." It's just the shell off a dead clam or something. But if you're asking if you can find them there, yes. There are seashells in New Jersey. They wash up on shore after the clam dies in them out at sea.
