WebAug 20, 2024 · Diatoms are one of several major types of marine phytoplankton. These microorganisms that live near the ocean surface and convert carbon dioxide into organic carbon via photosynthesis. They produce much of the oxygen we breathe and are the base of the marine food chain. WebA gel network is desirable for creating a physically robust structure, and is the morphology generally observed in diatom silica, although silica morphology can vary depending on cell wall features ( Round et al., 1990; Hildebrand et al., 2006 ). Silicic Acid Transport and Intracellular Stabilization WebWhen diatoms are present, a cleaning procedure of the frustules can be used before preparing the slides [34,35]. This procedure involves a careful use of some acids (nitric acid, hydrogen peroxide), able to remove the organic matter and carbonates from the sample, and therefore to highlight the morphological characteristics of the diatoms. filthy cities dan snow
