Significance of mitosis:

(l) To keep balance between Nucleus and Cytoplasm: The balance between nucleus and cytoplasm is maintained through mitosis so that the shape and size of the cell remain unchanged.

(2) Physical growth: In multi-cellular organisms a one celled zygote turns into a many celled embryo. Repeating the same process the embryo eventually forms the multi-cellular organism.

(3) Formation of reproductive organs: By equational division, reproductive organs are formed in the multi-cellular organism.

(4) Reproduction: In Eukaryotic organism, reproduction occurs by this process. (Such as in chlamydomonas)

(5) Keeping the chromosome number constant: Mitosis ensures the quantitative and qualitative distribution of chromosomes in all the cells of an organism.

(6) Repairing of Wounds: Any wounds or broken parts of the organisms can be repaired rapidly by mitosis.

(7) Demerits of mitosis: Turnour, cancer etc are caused by uncontrolled mitosis.
