Red algae, like Gracilaria, Gelidium, Euchema, Porphyra, Acanthophora, and Palmaria are primarily known for their industrial use for phycocolloids (agar, algin, furcellaran and carrageenan) as thickening agent, textiles, food, anticoagulants, water-binding agents, etc. [87] Dulse (Palmaria palmata) is one of the most consumed red algae and is a ...
Hypnea chordacea is a species of marine red algae found in the Indo-Pacific including Hawaiʻi. [1] It serves as an important food source for various marine organisms. [ citation needed ]
The consensus in 2005, when the group consisting of the glaucophytes and red and green algae and land plants was named 'Archaeplastida', [1] was that it was a clade, i.e. was monophyletic. Many studies published since then have provided evidence in agreement.
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. [2]
Polysiphonia, known as red hair algae, [1] is a genus of filamentous red algae with about 19 species on the coasts of the British Isles [2] and about 200 species worldwide, [3] including Crete in Greece, Antarctica and Greenland. [4] [5] Its members are known by a number of common names. [note 1] [4] It is in the order Ceramiales and family ...
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.
Cyanidiophyceae is a class of unicellular red algae within subdivision Cyanidiophytina, and contain a single plastid, one to three mitochondria, a nucleus, a vacuole, and floridean starch. [1] Pyrenoids are absent. [2] Most are extremophiles inhabiting acid hot springs.
Jania is an articulated coralline algae characterized by having erect thalli with dichotomously-arranged branches composed of alternating segments of red or pink, calcified, cylindrical sections (intergeniculum) and white uncalcified sections (geniculum); that is attached to the substrate by small, stolon-like holdfasts.
