Microtubles/Microfilaments/Intermediate Filaments?

Question

determine if the each of the following is true of microtubules, microfilaments, or intermediate filaments.

Involved in cell transport.

I'm stuck on whether to choose microfilaments or microtubules.
I know microtubules can create cilia or flagellum, which does involve with cell transport. And microfilaments can "crawl"

Answer 1

Microtubules : They are involved in maintaining cell shape, cell movement, Chromosome movement, and organelle movement. They are the largest so they do the biggest jobs.

Microfilaments: They also help in maintaining cell shape, muscle contraction, cytoplasmic streaming, formation of pseudopodia, and formation of the clevage furrow in cell division.

Intermediate filaments: Aid in cell shape, anchors the nucleus and other cellular organelles.

Answer 2

Microtubules are involved with internal cell transport. Consider a spindle made of microtubules. The spindle pushes and pulls the chromosomes into the right places during mitosis.
