Answer:
The structures that are responsible for the movement of chromosomes to the center of the cell in metaphase is the spindle fibers, the cell attaches the centromeres to the spindle fibers to pull the sister chromatids to the center
In anaphase the sister chromatids are separated at the centromere and are pulled to the opposite poles of the cell by the spindle fibers
Explanation:
The structures responsible for the movement of chromosomes to the center of the cell in metaphase and their separation in anaphase would be the spindle fibers.
The spindle fibers are formed from microtubules near the two poles of a dividing cell. Spindle formation starts from prophase and continues to grow and extend towards the centromere of chromosomes.
At metaphase, the spindle fibers would have successfully attached to each chromosome at the kinetochore of their centromeres. Once this is done, the spindle fibers start shortening, pulling sister chromatids apart towards opposing poles in the process.
The shortening of the spindle fibers serves as the vehicle that transports sister chromatids to the poles.
