to propel the cell through liquid
In wet mount preparations, is it possible to see eukaryotic flagella? prokaryotic flagella
Filamentous cytoskeleton is the cellular structure within the cytoplasm in every cell that helps it to keep its structure, protect the cell and allows cellular motion (using appendages like flagella, cilia, etc.). It also plays a role in intracellular transport and cellular division. The cytoskeleton is found in Eukaryotic and Prokaryotic cells.
Microtunles They have different structures. Eukariyotic 9+2 microtuble arrangement is absent in prokariyotes
Flagellum, (plural flagella) is mainly found on sperm, its the tail.
Eukaryotic flagella are quite different in structure and function to prokaryotic flagella.Bacterial flagella (as opposed to archaeal flagella - go to http://en.wikipedia.org/wiki/Flagellum#Archaeal to investigate differences between bacterial and archaeal flagella) are composed of the protein flagellin, which is coiled around into a stiff filament. Movement of a bacterial cell is generated by rotation of the filament, a bit how like a propellor works. Reversing direction of rotation can change direction of movement.In eukaryotic flagella, the structure is more complex. The base of the eukaryotic flagella houses the foundation of the structure. Nine microtubule groups, each consisting of three microtubules, form the base of the flagella. Further away from the cell, the flagella is made up of two microtubule's connected by a bridge. Radial spokes branch out to nine pairs of microtubules that form a circle around a flagella transverse section (if you chop it in half and look at the exposed inside).A eukaryotic flagella moves its cell by sliding adjacent pairs of microtubules, which causes the flagella to bend. This bending creates movement. To see a good example, watch this video: http://www.britannica.com/EBchecked/topic-video/209243/16501/Movement-of-eukaryotic-flagella-in-real-time-and-slow-motion

Yes,there are differences.Eukariyotic flagellum has 9+2 structure and membrane covered.Bacterial flagella do not have those.

They are in both.But differs from structure
Flagellum, (plural flagella) is mainly found on sperm, its the tail.
A flagellum( plural: flagella) is a tail-like projection that protrudes from the cell body of certain prokaryotic and eukaryotic cells.

cilia and flagella
A prokaryotic cell has smaller ribosomes then a eukaryotic cell, measuring 70S, rather then 80S in a eukaryotic cell. Prokaryotic cells have no nucleus and bacterial DNA is a single circular molecule. There are also no membrane organelles in a prokaryotic cell Flagella on a prokaryotic cell are simple hollow cylinders that are rigid and wave shaped, that rotate at the base (like a corkscrew motion). Eukaryotic flagella are found in circular arrangements of 9 with 2 in the middle of the bundle.
