WebMost diatom cells have a large central vacuole, or pair of vacuoles. During the stationary-phase of the cell cycle, cells often accumulate large quantities of lipids and fatty acids. Polyphosphate bodies are present, which may be apparent as spherical or complex 'volutin' granules. One polyphosphate body (only one) is located in a vacuole. WebCharacterization of diatom diversity requires accurate and consistent taxon identification. Morphological analyses alone fail to provide a complete description of diatom diversity …
