1. Daughter cells receive same number of chromosomes
as in parent cell. Thus it helps to maintain genetic integrity of the
species.

1. Daughter cells receive same number of chromosomes
as in parent cell. Thus it helps to maintain genetic integrity of the
species.
2. Since equal number of chromosomes are distributed to the daughter
cells, the daughter cells are similar to the parent cell quantitatively
as well as qualitatively.
3. It is responsible for the replacement of old cells
like those of the epidermis and blood corpuscles, having a short span
of life.
4. It promotes growth development of the organism.
In multicellular organisms, cell division either contributes
to the cell replacement from wear and tear of the body (regeneration)
or adds to the cell number, which results in the growth of the organism.
First meiotic division
Prior to meiosis some changes take place in the nucleus
in which DNA begins to replicate. It is sometimes known as interphase.
