Sargassum polycystum serves a multitude of purpose from its usage as fertilizer, human food (click on link for tasty and nutritious recipe! The brown colour of algae is due to the presence of large amount of xanthophyll called fucoxanthin. Laminaria is a source of food, manure, algin and iodine. The gametes fuse to form diploid zygote that germinates to produce diploid plant. The latter germi­nate to produce gametophytic thalli. It is phycocolloid which is obtained commercially from Laminaria, Macrocystis, Nereocystis, Fucus, Sargassum etc. Fertilization produces diploid zygote which germinates to produce diploid plant body. Male sex organs or antheridia produce uniflagellate sperms. 11. Alternation of generations is heteromorphic. The sargassum influx has been highly detrimental to this industry since 2011, and especially noticeable in 2015 and 2018 when large blooms took over the region’s beaches. Such a growth is called heterotrichous. 18. Sarganine is an antibacterial and antifungal extract obtained from it. The motile spores or zoospores are bi-flagellated and have heterokont flagellation with one smaller whip like smooth flagellum and other larger of tinsel type. The arrival of sargassum is not generally uncommon to beach areas, but in 2011, unusually large amounts started washing up on shore. To make matters worse, global temperatures have risen just over one-degree Fahrenheit every 10 years; the increased warmth being a catalyst for sargassum reproduction. Any number of the normally benthic species may take on Thickening mats of this algae block the sun from reaching coral reefs, leading to the decay and death of these structures, while rotting sargassum creates an increase in nitrogen and phosphorus levels in underwater communities. They can be found in several habitats such as freshwater, saline water, moist rocks, soil etc. Potash is abundant in Macrocystis and Nereocystis. Fixation to solid sub­stratum occurs through prostate portion and rhizoids. Ectocarpus.
