Germ cell
hideGerm cells are progenitors of the gametes. These singled-out cells move through the gut to the developing gonads and undergo mitotic proliferation followed by meiosis and differentiation into either eggs or sperm (mature gametes). Plants do not have a germ line set aside in early development. Instead germ cells can come from somatic cells in the adult floral meristem.
