| Abstract: | This paper deals with the morphology and ultrastracture of the mature egg of the scallop ( Chlamys farreri) . The surface of the egg is honey comb shaped and has no sign of polarity. The plasma membrane before fertilization is not a typical unit membrane and the form is abscure. The ooplasm posses mitochondria, endoplasmic retiiculum and Golgi body etc, but the centrilar complex is absent. The cortex posses cortical granules. The yolk has a different form and originated from many organelles. The nuclear phase of the mature egg is of metaphase of the first mature division. |
