Golden algae is also commonly used to refer to a single species, Prymnesium parvum, which causes fish kills. [4] The Chrysophyceae should not be confused with the Chrysophyta, which is a more ambiguous taxon. Although "chrysophytes" is the anglicization of "Chrysophyta", it generally refers to the Chrysophyceae.
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]
Hydrurus foetidus is a large freshwater alga found in a cold rivers. [1] It is a member of the chrysophytes, or golden algae. Distribution
Ochromonadales is an order of golden algae (class Chrysophyceae), a group of photosynthetic heterokonts (phylum Ochrophyta). [8] It initially contained numerous families united only by being primarily monadoid (flagellate), palmelloid or amoeboid throughout their life cycle .
Diatoms belong to a large group of protists, many of which contain plastids rich in chlorophylls a and c. The group has been variously referred to as heterokonts, chrysophytes, chromists or stramenopiles. Many are autotrophs such as golden algae and kelp; and heterotrophs such as water moulds, opalinids, and actinophryid heliozoa. The ...
Mallomonas is a genus comprising unicellular algal eukaryotes and characterized by their intricate cell coverings made of silica scales and bristles. [1] The group was first named and classified by Dr. Maximilian Perty in 1852. [2]
The haptophytes were first placed in the class Chrysophyceae (golden algae), but ultrastructural data have provided evidence to classify them separately. [13] Both molecular and morphological evidence supports their division into five orders; coccolithophores make up the Isochrysidales and Coccolithales.
Shortly after, unicellular chrysophytes were described by Otto Friedrich Müller. During this first era of scientific discovery, brown algae were described as plants, while microscopic algae were treated as animals under the name of infusoria. [19] During the 20th century, evolutionary and phylogenetic discussions began including heterokont algae.
