<P> As stored food , yolks are often rich in vitamins , minerals , lipids and proteins . The proteins function partly as food in their own right , and partly in controlling the storage and supply of the other nutrients . For example , in some species the amount of yolk in an egg cell affects the developmental processes that follow fertilization . The yolk is not living cell material like protoplasm , but largely passive material , that is to say deutoplasm . The food material and associated control structures are supplied during oogenesis . Some of the material is stored more or less in the form in which the maternal body supplied it , partly as processed by dedicated non-germ tissues in the egg , while part of the biosynthetic processing into its final form happens in the oocyte itself . </P>
