Cilia cell
They line the nose and breathing tubes of animals. They trap and remove dirt from the breathing systems. They have tiny hair like structures to remove mucus and dirt from the breathing tubes.

What is the Vacuole?
It is surronded by tonoplast and its cavity is filled with cell sap. It is large in plant cells. In animal cells it is absent or there are numerous very small ones.
