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 .
Its definition changed over time. In a 1957 classification of golden algae, French phycologist Pierre Bourrelly included in the order Ochromonadales all species that lack a cell wall and have a biflagellate stage during their life cycle, while those with a uniflagellate stage belonged to order Chromulinales .

Chloroplasts probably evolved following an endosymbiotic event between an ancestral, photosynthetic cyanobacterium and an early eukaryotic phagotroph. [17] This event (termed primary endosymbiosis) is at the origin of the red and green algae (including the land plants or Embryophytes which emerged within them) and the glaucophytes, which together make up the oldest evolutionary lineages of ...
This does not mean that brown algae completely lack specialized structures. But, because some botanists define "true" stems, leaves, and roots by the presence of these tissues, their absence in the brown algae means that the stem-like and leaf-like structures found in some groups of brown algae must be described using different terminology.

Charales is an order of freshwater green algae in the division Charophyta, class Charophyceae, commonly known as stoneworts.Depending on the treatment of the genus Nitellopsis, living (extant) species are placed into either one family or two (Characeae and Feistiellaceae).
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.
