NEET BIOLOGY

Detailed explanation-1: -Flagella are the organelles for bacterial locomotion.

Detailed explanation-2: -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-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: -The bacterial flagellar motor is powered by the transmembrane electrochemical gradient of ions, namely ion motive force (IMF) and rotates the flagellar filament to generate thrust to propel the cell body. The maximum motor speed reaches 300 revolutions per second in E.

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).
