The Chrysophyceae, usually called chrysophytes, chrysomonads, golden-brown algae or golden algae, are a large group of algae, found mostly in freshwater. [3] Golden algae is also commonly used to refer to a single species, Prymnesium parvum , which causes fish kills .
Chaetoceros is a genus of diatoms in the family Chaetocerotaceae, first described by the German naturalist C. G. Ehrenberg in 1844. [1] Species of this genus are mostly found in marine habitats, but a few species exist in freshwater. [2] It is arguably the common and most diverse genus of marine planktonic diatoms, [3] with over 200 accepted ...
Chrysophyta or golden algae is a term used to refer to certain heterokonts. Dinobryon sp. from Shishitsuka Pond, Tsuchiura, Ibaraki Prefecture, Japan. It can be used to refer to: Chrysophyceae (golden algae), Bacillariophyceae (diatoms), and Xanthophyceae (yellow-green algae) together. [1] E.g., Pascher (1914). [2]
Diatoms generate about 20 per cent of all oxygen produced on the planet each year, [26] and take in over 6.7 billion metric tons of silicon each year from the waters in which they live. [57] They produce 25–45% of the total primary production of organic material in the oceans, [ 58 ] [ 59 ] [ 60 ] owing to their prevalence in open-ocean ...
When its size becomes too small, a dividing diatom cell produces an auxospore to expand its cell size back to that which is normal for vegetative cells. [ 2 ] Auxospores can also play a role in sexual reproduction in diatoms, and may be formed after haploid gametes fuse to form a diploid zygote .

Diatoms generate about 20 per cent of the oxygen produced on the planet each year, [12] take in over 6.7 billion metric tons of silicon each year from the waters in which they live, [13] and contribute nearly half of the organic material found in the oceans. Diatoms are enclosed in protective silica (glass) shells called frustules.
