Diploid cells contain 2 sets of the same DNA where as haploid contains one set.....so our normal cells in our body (somatic cells) are diploid however our sex cells(gametic cells) which are the egg of a woman and sperm from a guy are only haploid which means they have only 1 copy of DNA......this is because they fuse with one another and add their DNA together to make a diploid cell
The statement is true. While mitosis's main function is to repair and grow, meiosis fulfills its function in reproduction, forming the egg and the sperm, the cells involved in the fecundation to form a new individual.
