Final answer:
Mitosis is a process that divides a single cell into two genetically identical daughter cells, with stages including prophase, prometaphase, metaphase, anaphase, and telophase, followed by cytokinesis. Skipping metaphase could result in unequal chromosome distribution, and spindle fibers play a crucial role in chromosome separation.
Step-by-step explanation:
Purpose and Phases of Mitosis
The purpose of mitosis is to divide a single cell into two genetically identical daughter cells, ensuring that each new cell has the correct number of chromosomes. This is crucial for growth, repair, and asexual reproduction in eukaryotic organisms.

Cytokinesis in Animal Cells
During cytokinesis, the cell's cytoplasm divides, creating two daughter cells. In animal cells, this is accomplished through a cleavage furrow that pinches the cell into two separate and complete cells.
If a cell skipped metaphase during mitosis, the daughter cells could end up with an incorrect number of chromosomes, leading to genetic disorders or cell death. Spindle fibers are significant as they facilitate the movement of chromosomes during mitosis, ensuring each daughter cell receives the correct number of chromosomes.
