Question

There are two different forms of cell division- mitosis and meiosis. Why do we need two forms? Do all cells use both forms? Why do you think that this is true? What are the advantages and disadvantages of each form of cell division?

Answer 1

Cell Divisions are of two types.

Explanation:

1. We need two types of cells divisions for different purposes.
2. Mitosis takes place in Somatic Cells and Meiosis occur in Germ Cells.
3. Mitosis helps in repairing and replacing old, damaged, dead cells.
4. Meiosis is needed for the continuation of race and also for maintenance of same number of chromosomes from one generation to the other.
5. Disadvantages: When the control on the cell division is lost, Somatic cells keep on dividing by mitosis which results in the formation of large number of cells. This condition is termed as Tumor.
