   Note: The ovum is a typical cell, with a cell wall, cell
         substance, nucleus, and nucleolus. In man and the

         contents, the vitellus; the nucleus, the germinal
         vesicle; and the nucleolus, the germinal spot. The
         diameter of the ripe ovum in man and the domestic
         animals varies between 1-200 and 1-120 of an inch.
