all cells should have 23 pairs of chromosomes except for the germline cells, ie sperm or egg which are only haploids, therefore only 23 chromosomes. Some cells have no nucleus, and therefore no chromosomes at all, ie blood platelets.
Meoisis occurs only in germline cells while mitosis only occurs in dividing cells.

hi
i am vikas a 14 yr old boy
all the cell of human body have 46 no. of chromosomes exept sex cells(germ cell)
the growth of our body takes place by mitosis(equational division)where the daughter cells have same no. of chromasomes as in their parent cell
the production of sperms(male gamete)& eggs(female gamete) takes place by miosis(reductional division)where 46 chromosomes are reducted into 23 chromosomes)
both male & female gametes have 23 chromosomes now
when they unite together to form zygote there will be 46 cromosomes. 23 from male gamete & another 23 from female gamete.
if u feel u can under stand this ,choose this as best answer
& add my id to ur add book

All of these have 23 pairs, or 46 in all. Of these, 22 pairs are called autosomes, the remaining two are the sex chromosomes.
