Detailed explanation-1: -The bacterial flagellum differs in composition, structure, and function from the eukaryotic flagellum, which operates as a flexible whip-like tail utilizing microtubules. The bacterial flagellum is rigid in nature and operates more like the propeller on a boat.

Detailed explanation-2: -A flagellum is a lash-like appendage that protrudes from the cells of certain bacteria and eukaryotic cells (such as sperm cells). The word flagellum is Latin for “whip". Organisms can have one or more flagella. Most organisms use their flagellum to move, but it also often acts as a sensory organelle.

Detailed explanation-3: -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.

Detailed explanation-4: -Euglena has a single whip-like structure located at one end of its body that pulls it through the water.

Detailed explanation-5: -In several bacterial species, such as E. coli, Pseudomonas aeruginosa, and Clostridium difficile, the flagellum is multifunctional and plays a role in motility and is an adhesive organelle.
