The difference between the diploid and haploid cells is that there are '2n' number of chromosomes in diploid cells while there are 'n' number of chromosomes in haploid cells. The diploid cells have same number of chromosomes as present in the parent cells while haploid cells have half number of chromosomes as compare to parent cells. Diploid cells are formed as a result of mitotic cell division while haploid cells are formed as a result of meiotic cell division. Moreover, diploid cells are formed in the somatic cells of the body while haploid cells are the sex cells which take part in reproduction.
Diploid cells have a full set of chromosomes ( 46) and haploid cells have only half that number ( 23). This is so that when sperm and ova ,that are haploid , unite they give the correct number of chromosomes again , 23+23=46. This then starts cell division for growth (mitosis)
Diploid means having a full set of chromosomes. Haploid means only having half a set of chromosomes as in the gametes , the ova and sperm. The ova and sperm have only half ( haploid) so that when both their nuclei join the full set of chromosomes is restored.
For humans a diploid human cell contains 46 chromosomes, which is 2 complete haploid cells or 23 homologous chromosome pairs.
I think hapliod cells have 23 chromosomes in a set and diploid cells have 46 chromosomes in a set. Diploid takes place in mitosis whereas haploid in mieosis.
Diploid cells are cells with full number of body chromosome while haploid cells are cells with the chromosme number of their gamete.
