Explanation:

Microfilaments:

They are made up of two chains made up of monomeric globular proteins called actin. The chains are coiled around each other.
They have a diameter of about 7 nanometre.
They help in cellular movement.

Intermediate Filaments:

They form strands which are made up of fibrous proteins like keratin, vimentin, desmin.
They have a diameter which ranges from 8 nanometre to 10 nanometre.
They have structural function and are required to maintain the cell shape and organelle position.

Microtubules:

They are formed when the globular proteins, alpha-tubulin and beta-tubulin form dimer and undergo polymerisation.
They have a diameter of about 25 nanometre.
They form the structural components of flagella, cilia and centrioles. They prevent cell compression.
