Explanation:
Detailed explanation-1: -Mitotic spindle formation is a critical event that takes place during prophase. Several events of mitosis depend on the mitotic spindle, which forms in the cytoplasm during prophase.
Detailed explanation-2: -Metaphase is the stage at which morphology (structure) of the chromosomes are studied. The spindle fibres attach to kinetochores of chromosomes during metaphase.
Detailed explanation-3: -The spindle apparatus that forms during mitosis is referred to as mitotic spindle whereas the one that forms during meiosis is called meiotic spindle. Spindle fibers are made up of microtubules and they appear as spindle-shaped structures (thus, the name). They develop outside the nucleus during mitosis.
