Which of the following is not a function of cytoskeleton in a cell?
1. Intracellular transport
2. Maintenance of cell shape and structure
3. Support of the organelle
4. Cell motility
 (a) Cytoskeleton is not associated with the intracellular: transport. The microtubules and microfilaments, are the components of cytoskeleton and are responsible for cellular and intercellular movements Rest of the options are functions of cytoskeleton is a Cell.
Cytoskeleton provides mechanical support to the cell that helps in maintaining cell shape and structure.
The cytoskeleton also keeps other organelles such as mitochandria and ribosomes separated from one another to avoid interference in one another's activities. It also helps in supporting the cell organelles.
