BRAINCAKEFlagella
The flagella of eukaryotes is made of microtubules with a 9+2 arrangement. Microtubules are assembled form a protein called tubulin.
Most motile bacteria move by means of flagella.
The flagella of prokaryotes are simpler and thinner filaments made from a protein called flagellin. The flagella do not have a 9+2 arrangement.
