Mitosis plant & animal
Mitosis is the process of cell division that produces two daughter cells with identical copies of chromosomes. It occurs in both animal and plant cells through the same stages: interphase, prophase, metaphase, anaphase, telophase, and cytokinesis. The key difference between animal and plant cell mitosis is that plant cells have cell walls that must form between the dividing cells.
