Question

Which type of cell division is required for growth and repair of body and which type is involved in formation of gametes?

Answer 1

Cell division: It is the process of formation of two daughter cells from a single cell following a series of steps.

Mitosis:

1. It is also known as equational division because it forms exactly a xerox copy of the previous cell.
2. The DNA amount remains constant and also the chromosome number remains constant in a species.
3. This is the cell division required for growth and repair of the body as it adds up identical cells to a certain part of the body increasing its size.

4. In case of injuries where the cells are damaged, mitosis occurs to repair those regions.

Meiosis:

1. It is known as the reductional division as the chromosome number reduces to half in this type of division.
2. It can form gametes as gametes need to be haploid cells so that they can fuse together in order to form a diploid zygote which will give rise to a new offspring.
