Red Algae - Polysiphonia (photosynthetic pigments) Chlorophyll a, phycoblin, arotenoids, phycoerythrin. part of the Viridiplantae (plant kingdom)

The genus Polysiphonia derives its name from the polysiphonous nature of its thallus. The central siphon is surrounded by 4–24 pericentral siphons. Polysiphonia is commonly found as an epiphyte on plants and lithophyte on rocks in brackish estuaries in the intertidal and sublittoral regions. Other articles where Polysiphonia is discussed: algae: Annotated classification: Kappaphycus, Palmaria, Polysiphonia, Porphyra, and Rhodymenia. Division Dinoflagellata (Pyrrophyta) Taxonomy is contentious. Predominantly unicellular flagellates; approximately half of the species are heterotrophic rather than photosynthetic; photosynthetic forms with Check Your Understanding.

Polysiphonia photosynthetic pigments

408-636- 408-636-3338. Pigment Delcarpenter. 408-636- 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. As a red-colored plant, Polysiphonia is well suited to absorb the green and blue-green light that typically penetrates the deeper seawater where these red algae thrive. In such a thallus differentiation occurs and distinction can be made between a cortical region providing rigidity and containing photosynthetic pigments. Triphasic life cycle: example of Polysiphonia Red algae are haplo-diplonts with a complicated life cycle that often involves three phases.

The life cycle of the red alga Polysiphonia. The photosynthetic pigments ( chlorophylls a and b, carotene, and xanthophyll) are in the same proportions as

The pigment phycoerythrin allows red algae to live and photosynthesize at these depths. Phycoerythrin absorbs blue light, which penetrates water to a greater depth than light of longer wavelengths normally used in photosynthesis.

Photosynthetic pigments derive their name from the fact they can absorb visible light (from Lat. pi(n)g(ere) - to paint + ment(um)). The molecules of photosynthetic pigments are quite ubiquitous, and are always composed of chlorophylls and carotenoids.
