The Cymbellales are a diatom order in the class Bacillariophyceae. They include the following families: [1]
Chlamydomonadales, also known as Volvocales, are an order of flagellated or pseudociliated green algae, specifically of the Chlorophyceae. Chlamydomonadales can form planar or spherical colonies. These vary from Gonium up to Volvox. Each cell has two flagella, and is similar in appearance to Chlamydomonas, with the flagella throughout the colony moving in coordination.
The Prorocentrales are a small order of dinoflagellates. They are distinguished by having their two flagella inserted apically, rather than ventrally as in other groups. One flagellum extends forward and the other circles its base, and there are no flagellar grooves. This arrangement is called desmokont, in contrast to the dinokont arrangement found in other groups. Accordingly, the Prorocentrales may be called desmoflagellates, and in some classifications were treated as a separate class Desmophyceae.
The glaucophytes, also known as glaucocystophytes or glaucocystids, are a small group of freshwater unicellular algae, less common today than they were during the Proterozoic. Only 15 species have been described, but more species are likely to exist. Together with the red algae (Rhodophyta) and the green algae plus land plants, they form the Archaeplastida. However, the relationships among the red algae, green algae and glaucophytes are unclear, in large part due to limited study of the glaucophytes.
Fucus vesiculosus, known by the common names bladder wrack, black tang, rockweed, bladder fucus, sea oak, cut weed, dyers fucus, red fucus, and rock wrack is a seaweed found on the coasts of the North Sea, the western Baltic Sea, and the Atlantic and Pacific Oceans. It was the original source of iodine, discovered in 1811 and was used extensively to treat goitre, a swelling of the thyroid gland related to iodine deficiency.
The Fucales (fucoids) are an order in the brown algae. The list of families in the Fucales, as well as additional taxonomic information on algae, is publicly accessible at Algaebase.
AlgaeBase is a global species database of information on all groups of algae, as well as one group of flowering plants, the sea-grasses.
Chaetophorales is an order of green algae in the class Chlorophyceae.
Oxyrrhis is a genus of dinoflagellates. It includes the species Oxyrrhis marina.
Nemoderma is the only genus in the family Nemodermataceae and order Nemodermatales of the brown algae. The genus contains only a single species, Nemoderma tingitanum.
Zygnema is a genus of freshwater filamentous thalloid alga comprising about 100 species. A terrestrial species, Z. terrestre, is known from India. Zygnema grows as a free-floating mass of filaments, although young plants may be found anchored to streambeds with a holdfast. The filaments form a yellow-green to bright green colored tangled mat, and are composed of elongate barrel-shaped cells, each with two star-shaped (stellate) chloroplasts arrayed along the axis of the cell.
Perkinsidae is a family of alveolates in the phylum Perkinsozoa, a sister group to the dinoflagellates.
Chrysomerophyceae is a monotypic class of photosynthetic heterokont eukaryotes.
Synchromophyceae is a class of photosynthetic heterokonts. The chloroplast of the Synchromophyceae are surrounded by two membranes and arranged in a way where they share the outer pair of membranes. The entire chloroplast complex is surrounded by an additional two outer membranes.
Mamiellophyceae is a class of green algae in the division Chlorophyta.
Pyramimonadophyceae is a class of green algae in the division Chlorophyta.
Syracosphaerales is an order of algae consisting of three families:
