Question

Which sentence correctly describes structures that help cells move?

Answer 1

Answer:

B and C

Explanation:

Option A is incorrect. Microtubules only support and give shapes to cells.

Option D is also incorrect because microfilaments mostly provide supports to cells as well.

The cilia is a slender protuberant structure found on some cells. A variant of the cilia (motile cilia) function in the locomotion of some unicellular eukaryotic organisms using wave-like actions.

The flagella is similar to the cilia in being protuberant as well as functioning as a locomotive structure. However, the flagella is much longer than the cilia and uses whip-like action instead of wave-like action.

Options B and C are correct.
