It alternates with short-lived gametophyte. Some algae such as Ulva, Polysiphonia, Ectocarpus, Kelps have a haplodiplontic life cycle. Difference Between

Professor (Dept. of Botany) 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.

Life-cycle The description and full understanding of the lif-cycle of the Florideophyceae is complex. The development of the gonimocarp, supporting cell, the auxiliary cell sterile filaments along with the correct definition of the pericarp, cystocarp, carpogonium, gonimocarp and carpogonium needs careful thought.Perhasps the article needs further stude. TYPE II Polysiphonia - occurrence , structure, reproduction & development is discussed with detail. Polysiphonia is a marine alga. It is present along the coast of oceans.

In life cycle of Polysiphonia two diploid phases carposprophyte and tetra sporophyte alternate with one haploid gametophytic phase. The life cycle of Polysiphonia can be called as triphasic diplobiontic with isomorphic alternation of generation (Figs. Moreover, why Polysiphonia is so called? The genus Polysiphonia derives its name from the
