Question

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?

a. Loss of basal bodies should lead to loss of all cilia, flagella, and centrioles.
b. Motor proteins such as dynein must have evolved before any of these four kinds of structures.
c. Natural selection for cell motility repeatedly selected for microtubular arrays in circular patterns in the evolution of each of these structures.
d. Cilia and flagella arise from the centrioles.
e. Cilia and flagella coevolved in the same ancestral eukaryotic organism.

Answer 1

Cilia and flagella arise from the centrioles

Step-by-step explanation:

Some cells have projections made up of microtubules and covered by extensions of the plasma membrane.

These projections can be cilia or flagella.

Centrioles are also made of microtubule from which the cilia and flagella arise. It also takes part during cell division

Basal bodies are protein structures found at the base of cilia and flagella. It functions as a site starting point for the growth of microtubule for the cilia and flagella
