The three different types of filaments differ in terms of polarity due to their constituent parts, called soluble subunits.

<h3>What is intermediate filaments?</h3>

The intermediate filament's subunits are elongated, not spherical, and they are linked together in an antipolar way.
Because of this lack of polarity in the overall filament, no motor proteins can move along intermediate filaments.
Only complex multicellular creatures contain intermediate filaments.
Intermediate filaments are more durable and essentially serve as the cell's structural framework.
Because the tubulin subunits that make up the microtubule are heterodimers of alpha and beta tubulin, the microtubule is structurally polar.
The microtubule's lattice is completely polarized along its whole length, not just at its two ends.
