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.

Polysiphonia species Polysiphonia elongata Name Synonyms Boryna elongata (Hudson) Bory, 1829 Ceramium brachygonium Lyngb., 1819 Ceramium elongatum (Hudson) Roth Ceramium elongatum var. denudatum (C.Agardh) Örsted, 1844 One of the many cyanotypes (or "sunprints") that make up Photographs of British Algae: Cyanotype Impressions (1843) by Anna Atkins, an English botanist and, some argue, the very first female photographer, most noted for using photography in her books on various plants. Sexual reproduction is oogamous. • e.g., Polysiphonia, Porphyra, Gracilaria and Gelidium 11. BRYOPHYTES (Amphibians of the plant kingdom) Bryophytes are also called amphibians of the plant kingdom because these plants can live in soil but are dependent on water for sexual reproduction. The life cycle of many red algae like Polysiphonia has an alternation of haploid and diploid multicellular generations. Economic Importance of Red Algae: The red algae like Porphyra (Laver) and Chondrus (Irish Moss) are cultivated in different countries as a food crop for human consumption.

In algae: Reproduction and life histories. …red algae, as exemplified by Polysiphonia, have some of the most complex life cycles known for living organisms. Following meiosis, four haploid tetraspores are produced, which germinate to produce either a male or a female gametophyte. When mature, the male gametophyte produces special spermatangial Occurrence of Polysiphonia: Polysiphonia is a large genus with about 200 species.

Polysiphonia (branching form) is a small marine alga. The filament is complex. Apical cells cut off proximal (A) - Dictyota, (B) - Polysiphonia. Dictyota is seaweed of class Phaeophyceae. They are marine and having laminarin, mannitol as their reserve foods.

The mass of gonimoblast filaments and the placental cell form he carposporophyte. The sexual reproduction in the Polysiphonia is oogamous which occurs in gametophyte and it is dioecious. The male sex organ is the spermatagia and the female sex organ is the carpogonia. The apices of the male plant bear the male trichoblast which is short and 2 celled.
