</h2>
Explanation:
Mitosis and meiosis result daughter cells for growth, development and reproduction in the living world.
Mitosis results two similar daughter cells which are generally for growth and development. In asexual mode of reproduction, mitosis helps in increasing the number of cells.
Meiosis occurs in germ cells, and in meiosis, one diploid cell produce four haploid cells.
Meiosis results variations by independent assortment and by crossing over and it helps the sexual mode of reproduction. During fertilization, the resultant daughter haploid cells unite and retains the diploid number of chromosomes.
