Cilium is an organelle that appears as a thin protuberance projecting from the larger cell body on eukaryotic cells.
Cilia are divided into two types: motile and non-motile, or primary cilia, which act as sensory organelles.
Cilia are essentially hair-like protrusions on the plasma membrane.
Their cilia are used for feeding and movement. Cilia are made up of microtubules and the motor protein dynein. Tubulin is a kind of globular protein that is made up of linear polymers.
Ciliary movement is defined as the rhythmic movement of cilia that generates fluid or cell movement. Eukaryotic cells include cilia.
Ciliary movement, for example, aids in the movement of the cell, which involves motility, as well as the movement of food within the cell in Paramecium.
