The cytoskeleton is a fibrous protein network that extends throughout the cytoplasm. Its primary function is to give mechanical support and maintain cell shape. In eukaryotes, it also has a significant role in the organization of the cell's activities.
Which of the following statements about the cytoskeleton is true?
A. Microfilaments are structurally rigid and resist compression, whereas microtubules resist tension (stretching).
B. Movement of cilia and flagella is the result of motor proteins causing microtubules to move relative to each other.
C. Transport vesicles among the membranes of the endomembrane system produce the cytoskeleton.
D. The dynamic aspect of cytoskeletal function is made possible by the assembly and disassembly of a large variety of proteins into complex aggregates.
E. Chemicals that block the assembly of the cytoskeleton would cause little effect on the cell's response to external signals and stimuli.
