Question

What is cell division and why it is necessary?

Answer 1

Cell division is the process of splitting a cell into two identical cells. Mitosis is the process of cell division in eukaryotes. Mitosis regulates cell growth, development, and repair in multicellular organisms.

It is important to create genetic diversity. In case of multi cellular organism, cell division helps maintain chromosome number in germ cells. In case of unicellular organism like Amoeba cell division is necessary for reproduction.
