	Red alga - Wikipedia, the free encyclopedia
		One red alga is a member of the red algae (Rhodophyta, pronounced /ˈrəʊdə(ʊ)ˌfʌɪtə/), which are a large group of mostly multicellular, marine algae, including many notable seaweeds.
		Their plastids formed by direct endosymbiosis of a cyanobacteria, and in red algae are pigmented with chlorophyll a and various proteins called phycobilins, which are responsible for their reddish color.
		The diverse eukaryotes that constitute the red algae have been the focus of numerous recent molecular surveys and remain a rich source of undescribed and little known species for the traditional taxonomist.

	Red alga - Biocrawler (Site not responding. Last check: 2007-10-22)
		The chloroplasts of red algae are bound by a double membrane, so presumably were acquired by direct endosymbiosis of cyanobacteria.
		Most other algae have chloroplasts taken secondarily from one of these forms, and in particular a number of groups appear to have acquired them from red algae: heterokonts, haptophytes, cryptomonads, and dinoflagellates.
		Molecular studies place the red algae in the kingdom Plantae; however, supraordinal classification has been largely confined to debate on subclass vs. class level status for the two recognized subgroups, one of which is widely acknowledged as paraphyletic.

	Section B - Red algae
		Red algae are unusual among the algae because they can include in their cell walls calcium carbonate which makes the plants hard and resistant to wear.
		Red algae are cropped and grazed by herbivorous animals such as fish, crustaceans, worms, gastropods.
		Red algae have some of the most complicated sexual cycles of any organisms, and some stages in their reproductive cycle are completely unknown.

	Olympus MIC-D: Oblique Gallery - Polysiphonia Red Algae
		Polysiphonia, a common genus of marine red algae, is red in color because of the pigment phycobilin, which masks the green color of the chlorophyll responsible for photosynthesis.
		Red algae often attach to submerged stones or anchor to other marine plants and are able to withstand the wave and tidal forces of the intertidal zone.
		These red algae are often used as vegetable substitutes for gelatin in puddings, ice cream, and toothpaste.

		The secondary metabolites in such seaweeds as Hormothamnium (blue-green alga) and Portieria (red alga) are noxious and serve as defense mechanisms against the numerous herbivorous fish and invertebrates that inhabit the waters around Guam.
