what is the difference between diploid and haploid cells?
A haploid cell contains only one set of chromosomes. Haploid cells are produced by meiosis. During meiosis, the chromosome number is halved from the diploid number to the haploid number. Similar to mitosis, in meiosis also, DNA replication takes place in the parent cell during the interphase.
A diploid cell contains two sets of chromosomes of which one is maternal, and the other is paternal. Diploid cells are produced by mitosis. During mitosis the parent nucleus divides into two daughter nuclei. Each daughter nucleus will contain the same number of chromosomes as the parent nucleus.
