Which statement BEST distinguishes typical cilia from flagella in eukaryotes?
- A
Cilia move only fluid; flagella never move cells
- B
Cilia have 9+2 microtubules; flagella have rotating filaments
- Ccheck_circle
Cilia are short and numerous; flagella are long and few - though both share 9+2 microtubule architecture
- D
Cilia exist only in plants; flagella only in animals
Explanation
Eukaryotic cilia and flagella both use a 9+2 microtubule axoneme; cilia are typically shorter and numerous, while flagella are longer and fewer per cell.
