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 .
Ochromonadales is an order of single-celled algae belonging to the class Chrysophyceae, also known as golden algae.Initially it contained numerous groups of flagellates that were not closely related.
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]
The name points to a character that is deemed to be synapomorphic for the group: that is the microtubular arrays that extend from the surface of the nucleus.Many flagellated forms have a single emergent flagellum, that lacks the root structure found in related chrysophytes.
The genus Mallomonas was first named and classified by Dr. Maximilian Perty in 1852. [2] It was assigned its own genus because Mallomonas consisted of individually living cells, while its sister group Synura is composed of colonial cells that are connected to one another through stalks.
Synura is the type and only genus in the family Synuraceae. [1] The present taxonomy recognizes five sections: [4] [5] Section Peterseniae S. americana; S. australiensis; S. borealis

The diagram depicts some mechanisms by which marine diatoms contribute to the biological carbon pump and influence the ocean carbon cycle. The anthropogenic CO 2 emission to the atmosphere (mainly generated by fossil fuel burning and deforestation) is nearly 11 gigatonne carbon (GtC) per year, of which almost 2.5 GtC is taken up by the surface ...
