WebThe number of flagella is comparatively less (usually ranges from 1 to 8) Cilia are usually shorter in length. Flagella are comparatively longer in length. The beating pattern of cilia is very complicated – It can move in a wide range of motions. The beating pattern of flagella involves circular, wave-like or propeller-like motion.
