of a eukaryotic cell plays a major role in organizing the structures and activities of the cell. The cytoskeleton consists of three main types of fibers: microfilaments, intermediate filaments, and microtubules. The three types of fiber differ in size, composition, and the functions they perform in the cell.

The difference between the microfilaments, intermediate filaments, and microtubules are stated below.

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.
