Commonly they are found in littoral and sublittoral zones. 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. The ends of the rhizoids are flattened into lobed discs called haptera, which assist the penetration of the host tissue ( Polysiphonia parasitic form) or confirm attachment to substrata. 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.
