The difference(s)between a cilium and flagellum is(are)
A)their internal structure and rate of beat.
B)their internal and external structure.
C)their external structure only.
D)their size,number,and beating pattern.
E)their primary source of energy.

Accepted Answer

The main difference between a cilium and a flagellum is their size, number, and beating pattern. Cilia are smaller and more numerous, with a coordinated beating pattern that helps move fluids or other substances across a surface. Flagella are typically larger and less numerous, with a whipping or undulating motion that propels a cell through an environment. While there may be some internal and external structural differences between the two, the primary functional difference is in their size, number, and beating pattern.
