Final answer:
Cilia are short, hair-like structures found on the epithelia of respiratory cells and uterine tubes. They are composed of microtubules and have a 9+2 array. They beat in unison and are used for locomotion, feeding, and movement of extracellular particles that come into contact with the cell.
