Detailed explanation-1: -Metaphase is a stage during the process of cell division (mitosis or meiosis). Normally, individual chromosomes are spread out in the cell nucleus. During metaphase, the nucleus dissolves and the cell’s chromosomes condense and move together, aligning in the center of the dividing cell.

Detailed explanation-2: -During metaphase, the cell’s chromosomes align themselves in the middle of the cell through a type of cellular “tug of war.” The chromosomes, which have been replicated and remain joined at a central point called the centromere, are called sister chromatids.

Detailed explanation-3: -Spindle fibers align the chromosomes along the middle of the cell nucleus. This line is referred to as the metaphase plate.

Detailed explanation-4: -Metaphase (the shortest phase of mitosis) is characterized by two events: Chromosomes line up across the middle of the cell. Spindle fibers connect the centromere of each sister chromatid to the poles of the cell.

Detailed explanation-5: -metaphase – chromosomes line up at the middle of the cell, along the plane of cell division, pushed and pulled by microtubules of the spindle apparatus. anaphase – sister chromatids separate and migrate towards opposite ends of the cell.
