Exploring Plant Mitosis

Mitosis is the process where a eukaryotic cell divides into two identical daughter cells. Initially, chromosomes are replicated and remain attached as sister chromatids. Mitosis begins with prophase, where chromatids condense and the nuclear membrane disintegrates. During metaphase, chromatids align at the cell's center. Anaphase follows, with sister chromatids separating and moving to opposite poles. In telophase, chromosomes reach the poles, and new nuclear membranes form. Cytokinesis completes the division, resulting in two cells with identical chromosomes.
