What are the difference in the flagella in prokaryotic and eucarkaryotic?

Answer 1

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.

Answer 2

Realy there is no difference between the two flaggela besides the fact that Eukaryotic cells only have 1 flagella and Prokaryotes have several or one. And also the thikness.

Answer 3

Both. Bacteria and protists are know to navigate through fluids with flagella.

Answer 4

Prokaryotic e.g. bacteria
