Cell division is the process of obtaining two daughter cells by the splitting of a single parent cell. According to the modern cell theory, new cells arrive from pre-existing cells. Therefore, cell division is the process of producing new cells from existing ones. Nuclear division and cytokinesis are the major steps in cell division.
Moreover, cell division is of two main types namely mitosis (vegetative cell division) and减数分裂(cell division for the formation of gametes). Vegetative cells divide by mitosis, and it is important for growth and repair and also for asexual reproduction. Similarly, the formation of gametes is an essential factor for sexual reproduction. Gametes are formed through meiotic cell division. Meiosis enhances genetic variation due to the fusion of male and female gametes, random distribution of chromosomes and crossing of between homologous chromosomes.
During mitosis, two daughter nuclei are produced with the exact number of chromosomes as the parent nucleus. But, meiosis results in four daughter nuclei with half the number of chromosomes concerning the chromosomes of the parent nucleus.
What are the Similarities Between Cell Division and Nuclear Division?
- Cell Division and Nuclear Division are two splitting events that take place during the cell cycle.

细胞分裂和核分裂都是两个泰pes of events that take place during the cell cycle. The key difference between cell division and nuclear division depends on the splitting process. Cell division is the process of splitting of a parent cell into daughter cells while the nuclear division is the process of parent nucleus into daughter nuclei. However, the nuclear division is one of the two steps of cell division. Both cell division and nuclear division are essential for the formation of new cells and gametes. Thus, this is the summary of the difference between cell division and nuclear division.
