Secretion of fatty and albuminous yolk by Golgi bodies in Stomopneustes variolaris, Lamarck

Abstract

1. The Golgi bodies in the oocytes of Stomopneustes secrete both fatty and albuminous yolk grains. 2. The Golgi vasicle enlarges into a vacuole inside which fatty yolk appears to be deposited. The Golgirim does not undergo any transformation. 3. Prior to secretion of albuminous yolk the mitochondria clump together. The Golgi vesicles by rupture give rise to scale or batonette like bodies. These attach themselves to the mitochondrial clumps and secrete albuminous yolk. The mitochondria in the fully developed yolk spheres are yolky. 4. The origin of both fatty and albuminous yolk in relation with the Golgi bodies only confirms the belief that the nature of the action of the apparatus is only by means of enzymes and that fat, fatty yolk and yolk are only secondary products resulting from the action of these enzymes on materials derived from mitochondria, cytoplasm, nucleolus, etc.
