» Diatom - Information on this unicellular organism of the kingdom Protista characterized by a silica shell of often intricate and beautiful sculpturing.




» Diatoms - Research project by John Becker provides plenty of information on these organisms and a modest photograph gallery.




» Diatoms: Pseudo-nitzschia - Research project by Jennifer Shin provides information on this organism and diatoms in general.




» Golden Algae - Information from Wikipedia on this large group of unicellular flagellate algae, the Chrysophytes, found mostly in fresh water.




» Introduction to the Chrysophyta - Brief discussion of the group, also called golden algae, which is found in fresh water, particularly lakes. Includes information on some subgroups.
