1) mitosis is a type of division which occurs in somatic cells. In mitotic cell division diploid number of chromosomes are present in the daughter cells i. e. the cell before division into two doubles it's chromosomes.

2) mitosis is important for growth, replacement of old cells, repair and damage of existing cells.

3) prophase, metaphase, anaphase, telophase are the four phases.

4) in the interphase or resting phase there is active synthesis of RNA and proteins

5) at the time of transformation of the cell from interphase---prophase the chromosomes gets duplicated

6) in anaphase the sister chromatids split into two by the contraction of spindle fibres and move to the poles of the cell

7) at the time of cytokinesis the cell divides into two due to the division of cytoplasm
