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.

Jul 14, 2017 - Polysiphonia General Characteristics: Thallus Organization, Siphon System, Sexual Reproduction, Post Fertilization Changes and Life Cycle of Polysiphonia (Red Algae) Characteristics of the life cycle of Brown algae Brown algae (Phaeophyta) are named after their typical brownish, olive green color caused by Fucoxanthine. This pigment is called after the alga Fucus (Bladder wrack; see here above), which is also abundant at the Dutch coast. Jul 14, 2017 - Polysiphonia General Characteristics: Thallus Organization, Siphon System, Sexual Reproduction, Post Fertilization Changes and Life Cycle of Polysiphonia (Red Algae) Floridean algae have numerous small chloroplasts and a complex life cycle. Bangean algae have life cycles without carpogonia and carposporophyte development and have a single central chloroplast. Representative species of Florideophyceae are Batrachospermum, Chondrus, Corallina, Gelidium, and Polysiphonia.

Polysiphonia shows isomorphic alternation of generation. 1. Gametophyte generation: The gametophyte plants produce. Gametes. The male gametes (spermatia) and female gametes (oosphere) fuse to form diploid nucleus. It is the beginning of the sporophytic stage. 2. Sporophyte generation: Diploid carpospores are produced on he carposporophyte.

Haploid gametophytic phase (2). Diploid carposporophytic phase (3). Diploid tetrasporophytic phase. Ø Thus the life cycle is with two diploid and one haploid phase and thus the life cycle of Polysiphonia is haplodiplobiontic. Polysiphonia shows an isomorphic alternation of generation. Both gametophytic (haploid) and sporophytic (diploid) generations are identical. Sexual reproduction occurs in gametophytic plants and the asexual reproduction occurs in sporophytic plants.

Polysiphonia forfex branching mainly on - shaped, tips d inwards 12. Haplodiplontic cycle is the life cycle which is intermediate between haplontic and diplontic. In this both the haplontic and diplontic are free living and multicellular. In diplontic life cycle the diploid sporophyte is dominant. Ectocarpus and fucus are algae which has both haplodiplontic and diplontic life cycle.

This life cycle present only in Bryophytes and pteridophytes. So, sphagum, polytrichum, marchantis and riccia belongs to Bryophyta and selaginella, pteris, dryopteris and polysiphonia belongs to pteridophyta.

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. 8, 9). Botany, Algae, Divisions, Rhodophyta, Polysiphonia.
