[Ultrastructural localization of acid and alkaline phosphatases in sterile septae of the anthozoa Pachycerianthus fimbriatus (author's transl)].
Acid and alkaline phosphatase activity has been localized in the cells of the sterile septae of starved and fed anthozoa. Acid phosphatase is present in lysosomes, in Golgi cisternae and old phagosomes of starved animals. In fed animals, the reaction is more intense and the number of lysosomes is increased. New phagosomes are loaded with lead phosphate. In starved animals, the alkaline phosphatase activity has been observed on the plasma membranes and in the old phagosomes.
