Abstract: | Summary Ultrastructural studies suggest that, in the oocytes of the lizardPodarcis sicula, ribosomal bodies are structurally continuous with annulate lamellae during their organization and disaggregation. This observation may indicate the dynamic transformation of the cytomembranes of one structure into those of the other, and vice versa. Moreover, the presence of annulate lamellae has been detected for the first time in lizard oocytes. The hypothesis is advanced that ribosomal bodies and annulate lamellae, in spite of some different structural characteristics, may play a similar role during the oocyte growth. |
