Life History of Polysiphonia. The red alga, Polysiphonia derives its name (Poly = many, siphon = tube) owing to its thallus organization with many interconnected  For example, the red alga Cyanidium lives in acidic (pH 2-4) hot springs at 55 identical, and therefore can be said to be isomorphic, as in the Polysiphonia. Floridean algae have numerous small chloroplasts and a complex life cycl They are related to land plants, but have one of the most complex life cycles among living organisms Above: Polysiphonia carposporophyte inside the pericarp. 31 Dec 2020 Ø The life cycle of Polysiphonia includes three phases (a).

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 Polysiphonia shows isomorphic alternation of generation. 1.
