Respuesta :
A cell is said to have reached the metaphase stage of mitosis when The equatorial plate now contains the centromeres.
What is metaphase stage?
A portion of cell division is known as "metaphase" . Individual chromosomes can be typically dispersed throughout the cell nucleus. The chromosomes of the cell condense and move toward one another, joining in the center of the developing cell, and the nucleus of the cell disintegrates during metaphase.
What is equatorial plate?
Plate equatorial is a configuration of chromosome centromeres that places them roughly in one plane near the spindle's equator. Meiosis or mitosis exhibit something during metaphase.
The cell in the image up top is already in metaphase. The chromosomes have aligned at the metaphase plate, the mitotic spindle gets fully grown, and the centrosomes are all at the opposite ends of the cell.
