Definition of Flagellum | What is Flagellum

Concept and Meaning of Flagellum

Derives from the latin flagellum flagellum (whip or whip; instrument used for spanking and that, being hit on someone, it causes pain and injury; a person can be whipped as punishment or in the middle of a sadomasochistic sexual practice, but can also will impose if she decides to whip as penance) and the verb flogging (beating lashes).
In the field of biology, the flagellum is the filiform filament which has the shape of a whip and found in many single-celled organisms and in some cells of multicellular organisms. Mobile, this flagellate allows to perform different movements and perform different functions according to the organization. Sperm, for example, have a flagellum which allows them to move.
The flagella are eukaryotic, bacterial and archaeal (of Archaea). Eukaryotic flagella are a cellular projection that allows to generate a helical motion. Bacterial flagella, in turn, are a complex mechanism in which the filament turns in the guise of a propeller. The archaeal flagella, finally, are similar to the bacterial but differ in many details.
