Abstract
Light and electron microscopy studies were made on dorsal leaves of Azolla filiculoides at different stages of development that corresponded to three different levels of nitrogen fixation in the plant. The morphological and histochemical studies referred to in this work showed a complex relationship between the three partners (Azolla, Anabaena, bacteria), with special emphasis on the biological recognition of these organisms in the symbiosis. The bacteria, present in all stages of leaf development, are in close association with the Azolla cavity cells and follow a location pattern identical to that of the cyanobacteria.
