Difference Between Cilia And Flagella. In this article, you will get to know about what are cilia, what are flagella, what is the main difference between cilia and flagella, and a comparison between cilia vs flagella. They both are organelles that are present in the cells. They both have an almost similar structure. But they are functionally different and different in size as well.

Difference Between Cilia And Flagella:

The main difference between cilia and flagella is that cilia are found in a eukaryotic cell. They are large in number and found abundantly in the cell. On the other hand, flagella are found in both prokaryotic and eukaryotic cells. They are fewer in every cell. Both are for the locomotion of the cells.

What Are Cilia?

Cilia is present on the surface of the cell. Cilia are referred to as short appendages. They are responsible for the locomotion of the cell. Cilia are hair-like structured that are short in length. They work as a motor and move in a rotational motion very quickly. There are hundreds of cilia present in a single cell. Eukaryotic cells contain cilia. The word cilia come from the Latin word eyelash.

Types Of Cilia:

Cilia are of two types, i-e. Motile cilia and non-motile cilia. The motile cilia are present on the surface of the cell. They have a rhythmic beating pattern. The inner lining of the windpipe also contains motile cilia. In the windpipe, they clean the lungs and dirt particles from the lungs. Motile cilia are also present in fallopian tubes. Non-motile cilia are present in every body cell. They do not have a rhythmic beating. They are present in the nose, eyes and other sensory organs of the body.

What Are Flagella?

Flagella are also responsible for the movement of the cell, just like cilia. The flagella are longer in length than cilia. They have a thread-like structure. They are present on the outer surface of the cell. Flagella can vary in size their length. They move very slowly as compared to cilia and have waves like movements. The number of flagella on a single is few, up to 10 on each cell. Both eukaryotic and prokaryotic cells have flagella. The word flagella come from the Latin word whip.

Types Of Flagella:

There are three types of flagella; Bacterial flagella, Archae flagella, and Eukaryotic flagella.

-Bacterial flagella have a helical shape. They have screw-like rotation. E-coli. and other bacterias have the bacterial type of flagella. They provide movement to the bacterias. Bacterial flagella may vary in numbers, they can be one, two, six or more in numbers.
-Archae flagella do not a certain channel. They are almost similar to the bacterial flagella.
-Eukaryotic flagella have very complex structures. Some common examples of them are flagella of sperm cells. The eukaryotic flagella propel the sperm cells to the female reproductive tract. Some men have flagellum dysfunction. The problem can lead to infertility because the sperm cell is not motile that it can reach the egg for fertilization
