Question

How does cilium differ from flagellum?

• A. Flagella have basal bodies situated at their base and cilia do not.
• B. A cilium's bases do not possess a 9+2 arrangement of microtubules
• C. Cilia appears in large numbers on the cell surface, flagella do not
• D. A cilium is typically longer than a flagellum

Answer 1

The correct option is C Cilia appears in large numbers on the cell surface, flagella do not

Cilia can appear in large number on the cell surface, flagella do not. In cells like paramecium, cilia is present all over it to help in its movement.
Both flagella and cilia both have basal bodies that play a major role in the assembly of these locomotory structure.
Both flagella and cilia exhibit 9+2 arrangement of microtubules. A flagellum is typically longer than a cilium.
