<P> In seed plants , the ovule is the structure that gives rise to and contains the female reproductive cells . It consists of three parts : The integument ( s ) , forming its outer layer ( s ) , the nucellus ( or remnant of the megasporangium ) , and the female gametophyte ( formed from a haploid megaspore ) in its center . The female gametophyte -- specifically termed a megagametophyte -- is also called the embryo sac in angiosperms . The megagametophyte produces an egg cell ( or several in some groups ) for the purpose of fertilization . </P>
