Describe the structure and function of the cytoskeleton

An organelle found in all eukaryotic cells made of thin microfilaments of the protein actin and microtubules made of the protein tubulin. Transport is the key role where motor proteins drag organelles from one part of the cell to another via the microtubule motor tracks. The cytoskeleton supports, strengthens and gives a structure to the cell. They maintain the shape of cell and allow organelles to move within the cell as well as for the entire cell to move. They form the key components of processes such as endocytosis in phagocytosis and exocytosis during protein synthesis. Microtubules also form spindle fibres in cell division and form cilia in the 9+2 arrangement for motor functioning in eukaryotic cells.
