The words that have slipped your mind are "flagellum on bacteria" and its microscopic, that's why I said "macroscopic". It's easy to make a part that moves in 360 degrees if its microscopic because nutriments can just diffuse in and waste products diffuse out; but as parts get bigger the volume increases by the cube of the radius but the surface area only increases by the square, so when things get big diffusion just isn't good enough. Evolution never figured out how to do better and make a wheel large enough to see, but people did.
