Detailed explanation-1: -Final Answer: Equatorial plate is formed during Metaphase.

Detailed explanation-2: -During metaphase, the chromosomes get arranged in the form of a plate called the equatorial plate or metaphase plate at the equator of the spindle.

Detailed explanation-3: -During anaphase A, the chromosomes move to the poles and kinetochore fiber microtubules shorten; during anaphase B, the spindle poles move apart as interpolar microtubules elongate and slide past one another.

Detailed explanation-4: -equatorial plate An arrangement of the centromeres of chromosomes in which they lie approximately in one plane, at the equator of the spindle. This is seen during metaphase of mitosis and meiosis.

Detailed explanation-5: -In Anaphase of mitosis: (I) Chromosomes move to equator and get aligned along metaphase plate. (II) Centromere of each chromosome is towards the equator when chromosomes move away from the equatorial plate.
