| Popis: | Measurements of particle densities on the two freeze-fracture faces of digestive and perialgal vacuole membranes in green and aposym biotic Paramecium bursaria Ehrbg. show distinct differences between the P-faces of both membrane types. The distribution of particle densities is more homogenous on the P-faces of perialgal vacuole membranes than on the P-faces of digestive vacuole membranes. Possibly homogeneity among peri algal vacuole membranes reflects the stability of perialgal vacuoles during their life cycle. Perhaps lysosomes cannot fuse with them. |
