Centrioles,cilia,flagella,and basal bodies have remarkably similar structural elements and arrangements.Which of the following hypotheses is most plausible in light of such structural similarities?

Question

Quizplus · Accepted Answer

The structural similarities between centrioles, cilia, flagella, and basal bodies suggest that they share a common evolutionary origin. The fact that cilia and flagella have the same microtubular arrangement as centrioles suggests that they may have evolved from centrioles. Additionally, studies have shown that when centrioles are disrupted, cilia and flagella fail to form in cells, further supporting the hypothesis that cilia and flagella are derived from centrioles.
