What Is a Long Hair-Like Structure Used for Movement?

Cilia and flagella are both hair-like structures used for the movement of eukaryotic cells. Both cilia and flagella can be found in plant cells as well as mammalian sperm cells.

Cilia and flagella are organelles that line the surface of eukaryotic cells. These hair-like protrusions move in waves, aiding in the movement of the cell. They are structurally similar, but cilia are shorter and often more numerous than flagella. Both are formed by microtubules that slide against each other, creating the motion that generates cellular movement. In addition to moving cells, cilia also aid in the movement of liquids, most commonly in the female reproductive system.
