 -  For example, replacement of diatoms with chlorophytes will alter cycling of silica because diatoms require silica and chlorophytes do not.
 -  Many are planktonic like the diatoms and Sargassum, floating free near the water surface, and being carried along by the surface currents.
 -  From single-celled algae called diatoms to the story of a man who plants acorns, IDFuel reminds us that inspiration for design is all around us.
 -  Algae, diatoms, dinoflagellates, and photosynthetic bacteria all belong to this group of organisms.
