★ MITOSIS :

=> Chromosomes number of parent cell maintained in two daughter cells is called mitosis.

• It means haploid cell (n) will form two haploid daughter cells.
• Diploid cell (2n) will form two diploid daughter cells.

★ MEIOSIS :

=> Chromosomes number of parents cells reduce to half in daughter cells is called meiosis.

• It means a single diploid cell will form two haploid cells.
• Here the Chromosomes number are reduce to the half.
