Abstract: The effect of the extracts of the optic tentacles on the synthesis of polysaccharides in the albumen gland of the land slug S. maculata have been studied with help of histochemical tests.It was observed that the acini of the gland contained both the glycogen and galactogen polysaccharides. The hormones in the tentacles increased the synthesis of galactogen and decreased synthsis of the glycogen.The accumulation of galactogen in this gland seems to be utilized for the synthesis of perivitelline fluid around eggs and the glycogen utilized for the synthesis of galactogen.Such interconversion of polysaccharides was found useful in the gametogenesis and for the nutrition and survival of gametes of slugs. Keywords: polysaccharides, optic tentacle, albumen gland, metabolism
