FLAGELLA Meaning and
Definition
-
Flagella (plural form of flagellum) refer to hair-like structures found in various organisms that facilitate movement or locomotion. These structures are primarily observed in single-celled organisms such as bacteria, archaea, and eukaryotic organisms like algae and protozoa. Flagella are composed of several microtubules, typically arranged in a circular pattern, surrounded by a thin cell membrane.
Functionally, flagella enable the movement of cells through fluid environments, assisting organisms in various biological processes. The waving or undulating motion of flagella propels the cell forward or backward, allowing it to navigate its surroundings or respond to external stimuli. Additionally, flagella may play crucial roles in other cell functions, including chemotaxis (movement towards a particular chemical substance), phototaxis (movement in response to light), or mechanotaxis (movement in response to touch or pressure).
Flagella can vary in number, length, and arrangement depending on the organism. For instance, some bacteria possess multiple flagella, which protrude from different locations on the cell surface. In contrast, other organisms may have a single, whip-like flagellum, such as the flagellum found in sperm cells.
Overall, flagella are vital structures that enable organisms to maneuver and interact with their surroundings efficiently, contributing to their survival, reproduction, and overall biological functions.

Etymology of FLAGELLA
The word "flagella" has its etymology in Latin. It comes from the Latin noun "flagellum", meaning whip or lash. The term "flagellum" itself is derived from the verb "flagellare", which means to whip or flog. The word "flagellum" was initially used to describe the long, whip-like appendages found in certain organisms, such as bacteria or protozoa, that help them with movement or propulsion. From there, "flagella" became the plural form of "flagellum" and is commonly used in biological contexts to refer to whip-like appendages or structures found in various organisms.
