WebA germ cell is any cell that gives rise to the gametes of an organism that reproduces sexually.In many animals, the germ cells originate in the primitive streak and migrate via the gut of an embryo to the developing gonads.There, they undergo meiosis, followed by cellular differentiation into mature gametes, either eggs or sperm.Unlike animals, plants do not …
