What are the four stages of cell mitosis?

The four phases are - prophase, metaphase, anaphase and telophase. This can be remembered as P-MAT. The first phase, prophase, is where the chromatids condense into chromosomes, making them visible. The second, metaphase, is where the now visible chromosomes line up at the equator of the cell (middle of the cell, m in metaphase for middle to help remember). Next, the third phase, is anaphase. This is where the sister chromatids separate (they are moving away from the equator, think a in anaphase for away). The centromeres, which are holding these sister chromatids together, also divide in this anaphase stage. The final stage is telophase, where the cytoplasm divides and two identical daughter-cells are formed.
