Question

which of the following statements about the cytoskeleton is correct? transport vesicles move between organelles of the endomembrane system independently from the cytoskeleton. microfilaments are structurally rigid and resist compression, whereas microtubules resist tension (stretching). movement of cilia and flagella is the result of motor proteins causing microtubules to move relative to each other. chemicals that block the assembly of the cytoskeleton would cause little effect on the cells response to external signals and stimuli.

Explanation:

Microfilaments are made of actin and resist tension, while microtubules are involved in cilia/flagella movement and vesicle - transport. Chemicals blocking cytoskeleton assembly would greatly affect cell functions. The endomembrane system is not independent of the cytoskeleton. Microfilaments resist tension and microtubules resist compression. Movement of cilia and flagella is due to motor - protein driven sliding of microtubules.

Answer:

None of the above options are completely correct as presented, but if we had to choose the most accurate - like statements in a more general sense: Microfilaments are more involved in resisting tension (stretching) and microtubules are important for maintaining cell shape by resisting compression and are also key in the movement of cilia and flagella as well as vesicle transport. However, the options seem to have some inaccuracies or incomplete information.
