Cilia picture
.Cilia are a fine projection from a eukaryotic cell that constantly beats in one
direction. It is structurally identical to the flagellum, but differs in that cilia are
much shorter and more numerous.

Cilia
In the body, cilia are responsible for protecting a person from germs in the
lungs and for pushing an ovum down the fallopian tube, among other tasks.
Similar to cilia, flagella are longer such hairs, usually found in ones or twos,
such as the "tail" of a sperm. They share many characteristics with cilia, but
they also occur on prokaryotes, which are organisms with cells that do not
contain a nucleus.
