Answer:
The fundamental functions of the cytoskeleton are involved in providing mechanical strength and integrity, enabling the movement of cells and facilitating the intracellular transport of supramolecular structures, vesicles and even organelles.
Step-by-step explanation:
In addition to the creation of an elastic environment within the cell interior, the cytoskeleton also plays important mechanical roles in linking the plasma membrane of the cell, as well as interior membranes such as the endoplasmic reticulum, to the rest of the cell, in limiting the diffusive motions of intracellular polymers that are larger than the network mesh size, and possibly in controlling the permeation of water and small solutes through the cytoskeleton.
