1A). The thalli may reach the length of about 30 cm. Polysiphonia General Characteristics: Thallus Organization, Siphon System, Sexual Reproduction, Post Fertilization Changes and Life Cycle of Polysiphonia (Red Algae) The key below for Polysiphonia uses more superficial characteristics of species than that described in the Flora, vol. IIID p. 170. Features of the genus Polysiphonia:  plants are often dark red-brown, almost black.

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. Thallus Structure of Polysiphonia: The thallus is filamentous, red or purple red in colour. The thallus is multi-axial and all cells are connected by pit connections hence, the name given is Polysiphonia. Due to continuous branching and re-branching the thallus has feathery appearance (Fig. 1A).

Are Phycoerythrin-phycocyanin aggregates and phycoerythrin aggregates showing special spectral characteristics were prepared from the partly dissociated products of phycobilisomes from Polysiphonia urceolata. The absorption difference spectra between the aggregates and phycoerythrins showing normal spectral characteristics show peaks at 583 nm. Majority of marine Red algae are this type (Polysiphonia) Major Classes of Algae (algal systematics) (1).

Post-fertilisation stage is much elaborate. 5. Cystocarp is well-developed. Polysiphonia Description. Polysiphonia is a red algae, polysiphonous and usually well branched, with some plants reaching a length of Distribution and ecology. Species have been recorded from Europe, Australia and New Zealand, North America and South Reproduction and life cycle. The life-cycle 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.

Polysiphonia hainanensis was previously described from Hainan, China, but DNA sequence had never been provided and its phylogenetic position in Polysiphonieae has not been clear so far. The classification of Polysiphonieae has changed recently based on the molecular analyses and detail morphological anatomy, consequently, the generic assignment of some species must be reassessed.

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. Polysiphonia is a heterotrichous alga having an erect series of branches and a filamentous prostrate section attached to the substratum by means of unicellular rhizoids.
