Explanation:
The cytoskeleton is also known as the cell skeleton that helps in the movement of the cell organelles. Three different types of cytoskeleton are microtubules, microfilaments and intermediate filaments.
The microtubules shows different function in different cell stages. During prophase stage of the cell cycle, the microtubules gets increase in length. During anaphase stage of the cell cycle , the nonkinetochore microtubules increase in the length the kinetochore microtubules gets short. During telophase stage of the cell cycle, the nonkinetochore microtubules gets disassemble.
Thus, the answer is true.
