Question

By which structure ciliary movement is carried out in protozoan

Answer 1

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 doublet microtubules, all of which are arranged with their (+) end at the outer tip of the axoneme.

Answer 2

Ciliary Movement: This type of movement occurs in most of our internal tubular organs.It includes the ciliated epithelium. The coordinated movements of cilia in the trachea help us in removing dust particles inhaled along with the atmospheric air. Also the passage of ova through the female reproductive tract is also performed by ciliary movement.
