Detailed explanation-1: -An adult filament of a multicellular, filamentous alga has the haplontic life cycle in which the meiotic division occurs after the formation of zygote. So, the filament of this alga has haploid vegetative cells and haploid gametangia.
Detailed explanation-2: -A multicellular, filamentous alga exhibits a type of sexual life cycle in which the meiotic division occurs after the formation of zygote.
Detailed explanation-3: -Filamentous algae (Spirogyra, Cladophora, and many other varieties) Common names: Pond scum, water net, frog spittle, moss.
Detailed explanation-4: -Spirogyra occurs in freshwater bodies such as ditches, ponds, lakes etc. It is multicellular filamentous green alga covered by a mucilagenous sheath. Each filament is unbranched and consists of cylindrical cells placed end to end.
Detailed explanation-5: -(c) Breaking up of Parent Alga gives rise to New Algae, this process is called Fragmentation.
