Answer :
Framework and anchor for organelles
The cytoskeleton is the ‘skeleton’ of a cell. It is an internal meshwork of 'scalfolding' composed of microtubules and microfilaments that extend through the cytoplasm and attached to the cell membrane.
Explanation:
They are mainly composed of actin, same fiber found in muscles, which are 3 – 6 nm in diameter. Through contraction and relaxation, they enable a cell to change shape when required such as during endocytosis or migration. They also form anchorage for organelles such as the Golgi apparatus, mitochondria, chloroplasts, and etcetera, in the cells.
