Which of the following statements about the cytoskeleton is correct?
A)Transport vesicles move between organelles of the endomembrane system independently from the cytoskeleton.
B)Microfilaments are structurally rigid and resist compression,whereas microtubules resist tension (stretching).
C)Movement of cilia and flagella is the result of motor proteins causing microtubules to move relative to each other.
D)Chemicals that block the assembly of the cytoskeleton would cause little effect on the cell's response to external signals and stimuli.

Question

Quizplus · Accepted Answer

Movement of cilia and flagella is indeed the result of motor proteins causing microtubules to move relative to each other. Option A is incorrect as the transport vesicles move along the cytoskeleton. Option B is incorrect as microfilaments resist tension whereas microtubules resist compression. Option D is incorrect as the cytoskeleton is essential for maintaining the shape of the cell and is involved in signal transduction.
