(N/A) $\Rightarrow$ An elaborate network of filamentous proteinaceous structures present in the cytoplasm is collectively referred to as the cytoskeleton. It is involved in many functions such as mechanical support,motility,and maintenance of the shape of the cell.
$\Rightarrow$ The cytoskeleton is formed by three types of fibers: Microfilaments,Microtubules,and Intermediate filaments.
$\Rightarrow$ Microfilaments are made up of proteins like Actin. They are scattered or arranged in parallel or in a network. They possess functions like amoeboid motion,movement or rotation of protoplasm,and translocation of materials. They are associated with cell motion or changes in the form of cells.
$\Rightarrow$ Microtubules are hollow tubes made up of tubulin protein. They help in maintaining the shape of the cell,cell motion,and cellular transport of materials. They are required for the translocation of chromosomes during cell division.
$\Rightarrow$ Intermediate filaments are durable,strong protein fibers. They form a basket-like structure of fibers and provide support to other fibers.
