Q.Which of the following is not a function of cytoskeleton in a cell?

Of the listed roles, intracellular transport is not one of the cytoskeleton's explicitly recognised functions in this chapter's account.

• The cytoskeleton's stated roles are mechanical support (holding cell components in place and giving structural strength), motility (enabling movement of the cell and of material within it), and maintenance of cell shape. …

The cytoskeleton is an elaborate network of protein filaments — microtubules, microfilaments and intermediate filaments — spread through the cytoplasm, acting as the cell's internal scaffold. Its recognised roles centre on three things: providing mechanical support, which holds the cell's internal components in place and gives it structural strength; enabling motility, both of the cell as a whole and of materials and structures inside it; and helping the cell maintain, and where needed change, its characteristic shape. …

Method: Matching Options Against the Textbook's Own Enumerated List

For a "which of these is NOT a function" question, the fastest reliable approach is to first recall the SPECIFIC, named list of functions the textbook itself gives for that structure — not everything you might know about it from other sources. For the cytoskeleton, the chapter names exactly three roles: mechanical support, motility, and maintenance of the shape of the cell.

Once you have that short list in hand, go through each answer option and check whether it is a restatement of one of those three named functions or something genuinely different. "Maintenance of cell shape" and "cell motility" map directly onto two of the three; "support of the organelle" is a specific instance of the general "mechanical support" function, so it also counts as covered. …
