Did you know?
The Coscinodiscophyceae are a class(s) of diatoms. They are similar to the Centrales, a traditional, paraphyletic subdivision of the heterokont algae known as diatoms. The order is named for the shape of the cell walls (or valves or frustules) of centric diatoms, which are circular or ellipsoid in valve view. The valves often bear radially symmetrical ornamental patterns that can appear as … WebFeb 21, 2024 · Diatoms.org represents such a content curation community, providing open, online access to a vast amount of recent and historical information on North American …
