Brown algae (sg.: alga) are a large group of multicellular algae comprising the class Phaeophyceae. They include many seaweeds located in colder waters of the Northern Hemisphere. Brown algae are the major seaweeds of the temperate and polar regions. Many brown algae, such as members of the order Fucales, commonly grow along rocky seashores.
Pseudochordaceae. Kelps are large brown algae or seaweeds that make up the order Laminariales. There are about 30 different genera. [3] Despite its appearance, kelp is not a plant but a stramenopile, a group containing many protists. [4]
Sargassum is a genus of brown macroalgae (seaweed) in the order Fucales of the Phaeophyceae class. [1] Numerous species are distributed throughout the temperate and tropical oceans of the world, where they generally inhabit shallow water and coral reefs, and the genus is widely known for its planktonic (free-floating) species.
Typically excluded. Cyanobacteria (blue-green algae) Embryophyta (land plants) Algae (UK: / ˈælɡiː / AL-ghee, US: / ˈældʒiː / AL-jee; [3] sg.: alga / ˈælɡə / AL-gə) is an informal term for any organisms of a large and diverse group of photosynthetic eukaryotes, which include species from multiple distinct clades.
Dead man's fingers (Codium fragile) off the Massachusetts coast in the United States. The top of a kelp forest in Otago, New Zealand. Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of Rhodophyta (red), Phaeophyta (brown) and Chlorophyta (green) macroalgae.
Laminaria is a genus of brown seaweed in the order Laminariales (kelp), comprising 31 species native to the north Atlantic and northern Pacific Oceans. This economically important genus is characterized by long, leathery laminae and relatively large size. Some species are called Devil's apron, due to their shape, [1] or sea colander, due to the ...
Brown algae have many unique characteristics in terms of their metabolism and cell biology. Ergo, brown algae and in particular, E. siliculosus, are often used for explorative research. Its genome was the first brown macroalgal genome to be sequenced, with the expectation that E. siliculosus will serve as a genetic and genomic model for brown ...
Species of Fucus are recorded almost worldwide. They are dominant on the shores of the British Isles, [5] the northeastern coast of North America [6] and California. [3]In the British Isles these larger brown algae occur on sheltered shores in fairly well defined zones along the shore from high-water mark to below low water mark.
