Question

What is The significance of mitosis cell dvivision and meiosis cell division?

Answer 1

meitosis creates new cells when things grow, repair damage
meiosis makes sex cells to make new organisms

Answer 2

The significance of mitosis cell division is the generation of daughter cells that have the same number of chromosomes as the mother cell. This occurs in almost all the cells in the body except the sex cells. The meiosis cell division generates gametes or sex cells that have only half of the number of chromosomes of the mother cells.

Answer 3

Mitosis is a replicative cell division involving one nuclear division to form 2 genetically identical daughter cells.

Significance of Mitosis:

The formation of new cells is necessary for the following reasons:
1. multicellular plants and animals start life as single cells, the zygotes or fertilized egg cells; the process of Mitosis gives rise to many cells which differentiate to form tissues, organs and organ-systems of the organism.
2. mitosis results in an increase in size and growth of an organism,
3. cell reproduction is used to form new cells to renew certain tissues and to replace worn out cells
4. mitosis is also used as a form of asexual reproduction in some organisms like in unicellular Amoeba and multicellular Hydra as well as vegetative reproduction in plants.


Meiosis is the process by which one diploid eukaryotic cell divides to generate haploid cells called gametes.

Four possible biological functions of meiosis are considered. First, the conventional view that it generates by recombination and sexual reproduction the genetic diversity on which natural selection can act. Second, that recombination at meiosis plays an important role in the repair of genetic defects in germ line cells. Third, that it is essential, at least in animals, for the reprogramming of gametes which give rise to the fertilized egg. Fourth, that it helps maintain the immortality of the germ line, possible by a process of rejuvenation involving the removal of faulty RNA and protein molecules, or by the elimination of defective meiocytes.

Answer 4

It would be 28 chromosomes. It takes 2 sex cells to determine the number of chromosomes, so just divide 56 by 2
