Abstract

The amount and distribution of the lysosomal enzyme acid phosphatase in light- and dark-adapted eyes of the brackish-water annelid Nereis limnicola were studied by standard cytochemical techniques. Precipitate from the acid phosphatase reaction was observed in Golgi-endoplasmic reticulum-lysosomal complexes, primary lysosomes, and secondary lysosomes, formed by fusion of primary lysosomes with phagocytic and pinocytic vesicles containing products of presumed rhabdomeric degradation. The acid phosphatase reaction occurred in these organelles in both sensory and supportive cells of both light- and dark-adapted ocelli. Secondary lysosomes were more abundant in sensory cells of illuminated ocelli than in those maintained in the dark. Sparse reaction product was found in Golgi cisternae, none in rough endoplasmic reticulum. We suggest that the increase of lysosomal activity in light-adapted eyes is correlated with the breakdown of photosensory microvilli upon exposure to light. A diagram of our interpretation of recycling of photoreceptoral membrane in N. limnicola is presented.
