Correct answer: C. Microtubules
- A. Microfilaments
- B. Microvilli
- C. Microtubules
- D. Intermediate filaments
Explanation
In a cross section, each centriole appears as a ring of nine triplets of microtubules. The microtubules in the triplets are arranged in a clockwise or counterclockwise direction. The triplets are connected to each other by proteins, and they form a rigid structure that is essential for the function of the centriole.
