Nice Question !!!
Answer :
The movement of Cilia and Flagella can be explained on the basis of three types of mechanisms :
(1) Cilia and Flagella are whip–like motile organelles present in a wide variety of eukaryotes . The force is exerted at its base.
(2) When the contraction takes place due to propagating wave contract at the inner curvature alternately forcing the opposite side to bend the cilium of flagellum from side to side.
(3) When the thin filament move past one another to produce a curvature in a sliding manner similar during muscle contraction. This filaments do not change their shape.
So as in the movement of muscle during contraction , the basis for axonemal movement is the sliding of protein filaments relative to one another. In cilia and flagella, the filaments are the double microtubules, all of which are arranged with their (+) end at the outer tip of the axoneme.
