Describe the general process of cell division. What is the most important change? What is the significance of this change?

During division, the nucleus is divided into two parts, and then the cytoplasm is divided into two parts, each of which contains a nucleus. Finally, a new cell membrane is formed in the center of the original cell (plant cells also form new cell walls).

Chromosome changes are most obvious when cells divide.

Significance: Because there is genetic material DNA in the chromosome, the genetic material contained in the new cell and the original cell is the same.

I wonder if it will help you. I hope it can be adopted ~!
