Origin and Continuity of Golgi Apparatus, which lack ribosomes. It is a complex structure with unique functions in compartmentalizing products of synthesis, serving as a site of cytomembrane differentiation and producing exocytotic vesicles whose membranes are capable of fusing with plasma membrane. Unlike semiautonomous organelles such as

Origin and Continuity of Cell Vacuoles,ork (1844) vacuoles became definitively regarded as normal morphological components of the plant protoplasm. With the advent of modern microscopes, after Ernst Abbe’s work, many cytologists have aimed at elucidating the structure of vacuoles, which formed the subject of a long and well-known essay b

While the general acceptance of the theory of differential gene activity as the basic epigenetic mechanism is an important advance in our understanding of development, it is only more recently that the presence of organized cytoplasmic “information” in the egg is recognized to

Origin and Continuity of Polar Granules, the insect orders Diptera, Hymenoptera, and Coleoptera. Their developmental significance was indicated morphologically, in that they were incorporated into one or more cells which then gave rise to the primordial germ cells of the embryo, and then experimentally, by .
