Flagella of prokaryotic and eukaryotic cells differ in

1. type of movement and placement in cell
2. location in cell and mode of functioning
3. microtubular organization and type of movement
4. microtubular organization and function

Correct answer: microtubular organization and type of movement

Solution

Eukaryotic flagella have a 9+2 microtubule arrangement and move with whip-like bending. Prokaryotic flagella are not microtubule-based; they are made of flagellin and rotate, so the key differences are microtubular organization and type of movement.
