Coralline algae are red algae in the order Corallinales. They are characterized by a thallus that is hard because of calcareous deposits contained within the cell walls. The colors of these algae are most typically pink, or some other shade of red, but some species can be purple, yellow, blue, white, or gray-green.
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.
Microalgae. Microalgae or microphytes are microscopic algae invisible to the naked eye. They are phytoplankton typically found in freshwater and marine systems, living in both the water column and sediment. [1] They are unicellular species which exist individually, or in chains or groups. Depending on the species, their sizes can range from a ...
Nannochloropsis is a genus of algae comprising six known species. The genus in the current taxonomic classification was first termed by Hibberd (1981). [2] The species have mostly been known from the marine environment but also occur in fresh and brackish water. [3] All of the species are small, nonmotile spheres which do not express any ...
Cyanobacteria (blue-green algae) Algae (UK: / ˈælɡiː / AL-ghee, US: / ˈældʒiː / AL-jee; [ 3 ]sg.: alga / ˈælɡə / AL-gə) are any of a large and diverse group of photosynthetic, eukaryotic organisms. The name is an informal term for a polyphyletic grouping that includes species from multiple distinct clades.
Marine protists are defined by their habitat as protists that live in marine environments, that is, in the saltwater of seas or oceans or the brackish water of coastal estuaries. Life originated as marine single-celled prokaryotes (bacteria and archaea) and later evolved into more complex eukaryotes. Eukaryotes are the more developed life forms ...
Turbinaria contains fucoxanthin which is a carotenoid pigment found in all brown algae. Its functions lie in the harvesting of light and energy transfer. [ 4 ] The genus has high levels of iron (893.7 ± 210.5 g −1 μg dry weight), [ 20 ] and has an affinity for arsenic and nickel, depending on the concentrations in the environments in which ...
Caulerpa prolifera. (Forsskål) J.V. Lamouroux, 1809 [2] Species [1] About 101. Caulerpa is a genus of seaweeds in the family Caulerpaceae (among the green algae). They are unusual because they consist of only one cell with many nuclei, making them among the biggest single cells in the world.
