Question

The similarity between plant and animal flagella microtubules is

• A. 9+3
• B. 9+2
• C. 9+6
• D. 9+1

Answer 1

Answer: (B)

9+2

A flagellum is a motile appendage that protrudes from the cell body of certain prokaryotic and eukaryotic cells. An eukaryotic flagellum is a bundle of nine fused pairs of microtubule doublets surrounding two central single microtubules. The so-called "9+2" structure is characteristic of the core of the eukaryotic flagellum called an axoneme.
