Dear Student,
Mitosis and meiosis are the two types of cell division.
a) Mitosis is the type of cell division in which the number of chromosomes in the parent cell and the daughter cells remain same. It occurs in all cells other than reproductive cells. It is also called equational division.
b) Meiosis is the specialised kind of cell division that reduces the chromosome number by half (thus called reductional division) resulting in production of haploid daughter cells (gametes). It mainly takes place in the reproductive cells or sex cells.
Regards!
