Detailed explanation-1: -The flagellum is the locomotory structure of motile bacteria. These are hair-like appendages originating from the basal body coming out through the cell walls. These help in movement of bacteria. It has three distinct parts: the filament, the hook (sheath), and the basal body.

Detailed explanation-2: -Two types of surface appendage can be recognized on certain bacterial species: the flagella, which are organs of locomotion, and pili (Latin hairs), which are also known as fimbriae (Latin fringes). Flagella occur on both Gram-positive and Gram-negative bacteria, and their presence can be useful in identification.

Detailed explanation-3: -Bacterial flagella are filamentous organelles that drive cell locomotion. They thrust cells in liquids (swimming) or on surfaces (swarming) so that cells can move toward favorable environments.

Detailed explanation-4: -Flagella-Flagella (singular, flagellum) are hairlike structures that provide a means of locomotion for those bacteria that have them. They can be found at either or both ends of a bacterium or all over its surface.

Detailed explanation-5: -Flagella are microscopic hair-like structures involved in the locomotion of a cell. The word “flagellum” means “whip”. The flagella have a whip-like appearance that helps to propel a cell through the liquid. Some special flagella are used in few organisms as sensory organs that can sense changes in pH and temperature.
