Mitosis or Mitotic Cell Division

Mitotic cell division is a type of cell division which occurs in somatic cells of the body for growth and for repairing old/injured cells. 

The chromosomes number the newly formed cells remain the same as in the mother or dividing cell.

12 Important Significance of Mitosis

12 Important Reasons which shows why mitosis is important is as follows –

1. Mitosis is responsible for the development of the zygote into an adult.The growth of multicellular organisms is due to Mitosis.
2. Mitosis is important in growth or increase in the body size due to formation of new cells in the tissues.
3. Mitosis is important for sexual reproduction indirectly. It allows the sexually reproducing organism to grow and develop from a single cell into a sexually mature individual.
4. This allows organisms to continue to reproduce through the generations.
5. It is responsible for a definite shape, and proper growth and development of an individual.
6. It maintains the constant number of chromosomes in all body cells of an organism.
7. Replacement of the old and dead cells such as the replacement of the blood cells and the epidermal cells of the skin.
8. A very significant contribution of mitosis is cell repair.In plants, mitosis helps in the formation of new parts and in the repairing of damaged parts.It repairs damaged and wounded tissues by renewal of the lost cells.
9.  Mitosis helps in vegetative propagation of crops also.
10. Mitotic divisions in the meristematic tissues – the apical and the lateral cambium, result in a continuous growth of plants throughout their life.
11. Since no recombination and segregation occurs in the process, Mitosis helps in maintaining the purity of types.
12. Asexual reproduction in which the unicellular organisms, such as amoeba or the yeast cell, divide into two with mitosis.
