transport of material inside the cell response of the cell to external pathogens storage of energy in stable long-term forms direction of cellular activity
I gave my students this multiple choice question: Which cell function is most directly dependent on the cytoskeleton?

Only one answer is correct among these 4 choices:
- transport of material inside the cell
- response of the cell to external pathogens
- storage of energy in stable long-term forms
- direction of cellular activity

Could you tell me which one is correct?
