Answer:

1.Microtubules are responsbile for moving Chromosomes to the metaphase plate. During Prometaphase, microtubules grow into a region around the Chromosomes until they find a Kinetochore. A Microtubule from each spindle pole connects to the kinetochore of each Chromosome.

2.Anaphase: Spindle fibers shorten and pull sister chromatids toward spindle poles. Separated sister chromatids move toward opposite cell poles. Spindle fibers not connected to chromatids lengthen and elongate the cell to make room for the cell to separate.

3.Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.
