Bangiophyceae

Nori is a dried edible seaweed used in Japanese cuisine, usually made from species of the red algae genus Pyropia, including P. yezoensis and P. tenera. It has a strong and distinctive flavor, and is generally made into flat sheets and used to wrap rolls of sushi or onigiri (rice balls).

Porphyra is a genus of coldwater seaweeds that grow in cold, shallow seawater. More specifically, it belongs to red algae phylum of laver species (from which comes laverbread), comprising approximately 70 species. It grows in the intertidal zone, typically between the upper intertidal zone and the splash zone in cold waters of temperate oceans. In East Asia, it is used to produce the sea vegetable products nori (in Japan) and gim (in Korea). There are considered to be 60–70 species of Porphyra worldwide and seven around Britain and Ireland, where it has been traditionally used to produce edibl

Bangiophyceae is a class of red algae that includes the order Bangiales and possibly Goniotrichales. In some classifications it is merged with the Florideophyceae to form the Rhodophyceae. The Bangiophyceae, as defined traditionally, are paraphyletic. Their taxonomic identification has been difficult because of a lack of distinct morphological features, and the presumed morphological plasticity of the species. Molecular tools are required to elucidate the relationships within this assemblage.

Bangia is an extant genus of division Rhodophyta that grows in marine or freshwater habitats. Bangia has small thalli with rapid growth and high reproductive output, and exhibits behavior characteristic of r-selected species. The plants are attached by down-growing rhizoids, usually in dense purple-black to rust-colored clumps. The chloroplasts of Bangia, like others in the division Rhodophyta, contain chlorophyll a and sometimes chlorophyll d, as well as accessory pigments such as phycobilin pigments and xanthophylls. Depending on the relative proportions of these pigments and the light condi

Pyropia is a genus of red algae in the family Bangiaceae. It is found around the world in intertidal zones and shallow water. The genus has folding frond-like blades which are either red, brown or green. Some Pyropia species are used to create nori, and are thus important subjects for aquaculture.

Bangiales is an order of multicellular red algae of the class Bangiophyceae containing the families Bangiaceae, Granufilaceae, and possibly the extinct genus Rafatazmia with one species, Rafatazmia chitrakootensis. They are one of the oldest eukaryotic organisms, possibly dating back to 1.6 billion years old. Many species are used today as food in different cultures worldwide. Their sizes range from microscopic (Bangiomorpha) to up to two meters long (Wildemania occidentalis). Many of its species are affected by Pythium porphyrae, a parasitic oomycete. Similar to many other species of red

Bangiaceae is a family of red algae in the order Bangiales. It contains laver, used to make laverbread, and various species in the genus of Pyropia are used to make nori.

Bangiomorpha pubescens is a species of red algae in the order Bangiales. It is the first known sexually reproducing organism. A multicellular fossil of Bangiomorpha pubescens was recovered from the Hunting Formation in Somerset Island, Canada that strongly resembles the modern red alga Bangia despite occurring in rocks dating to , during the Stenian period. This species is the oldest example of an organism belonging to an extant phylum. The fossil includes differentiated reproductive cells that are the oldest evidence of sexual reproduction. Sexual reproduction increased genetic variation, whi
