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 .
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 belong to a large group called the heterokonts, which include both autotrophs such as golden algae and kelp; and heterotrophs such as water moulds.The classification of heterokonts is still unsettled: they may be designated a division, phylum, kingdom, or something intermediate to those.
The best part of the science fair, Recio said, is testing out experiments. Third grade student William Kim admires a winning science fair project on ants at Miller High School on Friday, Jan. 19 ...
A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.
At the time when biologist Carl Linnaeus (1707–1778) published the books that are now accepted as the starting point of binomial nomenclature, Latin was used in Western Europe as the common language of science, and scientific names were in Latin or Greek: Linnaeus continued this practice.
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.

Some modern authors prefer to exclude multicellular organisms from the traditional definition of a protist, restricting protists to unicellular organisms. [ 9 ] [ 10 ] This more constrained definition excludes all brown , the multicellular red and green algae , and, sometimes, slime molds (slime molds excluded when multicellularity is defined ...
