Detailed explanation-1: -Flagella propel the cell by spinning around their axis in a corkscrew motion. They move in response to a chemical concentration gradient, indicating a sensory feedback regulation system. This is the basis for bacterial chemotaxis.
Detailed explanation-2: -Flagella are filamentous protein structures found in bacteria, archaea, and eukaryotes, though they are most commonly found in bacteria. They are typically used to propel a cell through liquid (i.e. bacteria and sperm).
Detailed explanation-3: -A flagellum is a whip-like structure that allows a cell to move. They are found in all three domains of the living world: bacteria, archaea, and eukaryota, also known as protists, plants, animals, and fungi. While all three types of flagella are used for locomotion, they are structurally very different.
