Mitosis occurs in somatic cells whereas meiosis occurs in reproductive cells.

In mitosis, the daughter cells have same number of chromosomes as parent cells whereas in meiosis, the daughter chromosomes have half the number of chromosomes as parent cells.

In mitosis, 2 daughter cells are formed from one parent cell whereas 4 daughter cells are formed in meiosis.

Mitosis helps to achieve growth of body and also repair of tissues. Meiosis conserves the chromosome number in a sexually reproducing species, from one generation to the next.

Mitosis involves a single division whereas meiosis involves 2 successive divisions.

Crossing over and pairing of homologous chromosomes occurs in meiosis but not in mitosis.

Meiosis helps in evolution because it introduces genetic variations. Mitosis does not help in evolution.
