Detailed explanation-1: -The types of appendages in bacteria are flagella, fimbriae and pili. And they are used for motility and attachment. A flagellum is a whip-like structure that allows a cell to move.

Detailed explanation-2: -The overall functions of these appendages are to provide motility and attachment to the bacterial cell. The bacterial flagellum is a whip-like structure that assists in a cell’s motility. It is a rigid structure and is made out of a filament, a hook, and a flagellar motor.

Detailed explanation-3: -Fimbriae are thin filamentous appendages that extend from the cell, often in the tens or hundreds. They are composed of pilin proteins and are used by the cell to attach to surfaces. They can be particularly important for pathogenic bacteria, which use them to attach to host tissues.

Detailed explanation-4: -There are different types of motility, often classified as swimming, swarming, twitching, gliding, and sliding [3, 4]. Swimming consists of movement in a liquid environment typically by using flagella, long, thin appendages attached to the cell [1].

Detailed explanation-5: -Flagellum is primarily a motility organelle that enables movement and chemotaxis. Bacteria can have one flagellum or several, and they can be either polar (one or several flagella at one spot) or peritrichous (several flagella all over the bacterium).
