The cytoskeleton is made up of protein threads. It is responsible for holding the cell in place, maintaining cellular shape and supporting the cell membrane. Plant and animal cells contain three basic types of protein thread. Actin filaments, or microfilaments, are the thinnest type, while intermediate filaments are thicker and stronger. Microtubules are larger still with a hollow center and are essential for mechanical support.
The cytoskeleton of a cell is made up of microtubules, actin filaments, and intermediate filaments. These structures give the cell its shape and help organize the cell's parts. In addition, they provide a basis for movement and cell division.ll cytoskeletons consist of three major classes of elements that differ in size and in protein composition. Microtubules are the largest type of filament, with a diameter of about 25 nanometers (nm), and they are composed of a protein called tubulin.
