The model of cell mitosis consists of 8 parts. The nuclear division mainly shows that it starts from the appearance of chromosomes in the nucleus, goes through a series of changes, and finally divides into two daughter nuclei. The model shows the 5 main stages of the nuclear division process: interphase, prophase, metaphase, anaphase, anaphase until two new daughter cells. Cytokinesis mainly shows the process of forming a new cell wall between two new daughter nuclei, dividing a mother cell into two daughter cells, and the nuclear membrane is completely transparent; in the model of each period of the whole process of division, it is also shown separately Nuclear mold, nucleolus, chromosomes, cytoplasm, spindle, cell plate and other major structures.
