This might be taken as an indication that the plastid, too, is a specialized sort of chondriosome comparable to the "; However, in view of the previous comparison between the plastid and the Golgi zone and the part played by the plastid in the elaboration of the limosphere, this is hardly possible. The role of the plastid in the latter respect is identical with that of the classical Golgi body, it elaborates the apical body or acrosome. Parat claims that the "lepidisomes" do not enter into the elaboration of the acrosome. He, however, stresses the fact that they are in an intimate relation with the Golgi zone up until the deposition of the acrosome. Exactly at this time they move away from the zone and pass down the tail of the maturing sperm. It seems that Parat may have missed one of the most important steps in spermatogenesis, the elaboration of the acrosome by the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
