The document summarizes the stages of mitosis in a plant cell: 1) In prophase, the chromatin condenses and the nucleolus begins to disappear as the mitotic spindle starts to form. 2) By late prophase, discrete chromosomes form consisting of two identical sister chromatids and the nuclear envelope fragments. 3) In metaphase, the chromosomes align in the center of the cell attached to microtubules at their kinetochores.
