Centrioles are small cylindrical structures that are present in eukaryotic cells.
It is a type of cytoplasmic organelle that plays a very important role in animal cells and in cells of lower plants (mosses and ferns).
Occupation
Centrioles are cellular structures that help in cell division (mitosis and meiosis).
Therefore, they have the ability to duplicate during the cell division cycle, organizing the achromatic spindle.
After the duplication process, the centrioles migrate towards the cell poles. Furthermore, they help in the formation of eyelashes and flagella.

Structure
Centrioles have a simple cylindrical-shaped structure not coated with membrane. They are formed by nine triple hollow microtubules.
Representation of Centrioles
They are made up of proteins and are located near the nucleus, a place called the centrosome or cell center.

(ciliates and flagellates), the centrioles help in the formation of two filaments called cilia and flagella.The cilia are short and numerous filamentous structures that aid in locomotion. In the human body, eyelashes are present in the trachea and are intended to capture and remove impurities arising from breathing.
Likewise, flagella aid in locomotion and also in feeding some protozoa (flagellates). However, they are less numerous than eyelashes.

Flagella have an elongated shape that resembles a whip. In the human body, male gametes (spermatozoa) are formed by flagella.
