Detailed explanation-1: -Cilia are small, slender, hair-like structures present on the surface of all mammalian cells. They are primitive in nature and could be single or many. Cilia play a major role in locomotion. They are also involved in mechanoreception.

Detailed explanation-2: -Ciliary locomotion Cilia operate like flexible oars; they have a unilateral (one-sided) beat lying in a single plane. As a cilium moves backward, it is relatively rigid; upon recovery, however, the cilium becomes flexible, and its tip appears to be dragged forward along the body.

Detailed explanation-3: -These tiny hairs wave back and forth, pulling in odor molecules and sending them to the brain for processing. Cilia also aid in moving dust and mucous out of your body, sweeping them from your nose down through the throat and the rest of the GI tract, where they can be flushed out of your system.

Detailed explanation-4: -Ciliates are protozoans that possess cilia which they use for both locomotion and feeding.

Detailed explanation-5: -Cilia are slender, microscopic, hair-like structures or organelles that extend from the surface of nearly all mammalian cells. They are primordial.
