Algae are heterogeneous, polyphyletic assemblage of very simple, water loving, autotrophic organism having no sterile layer of jacket-cells around their reproductive organs and lacking true embryogenesis. As primary producers, they are an important component of aquatic ecosystem, being inhabitants of moist, freshwater, brackish water and marine environments of our biotope. Right up from the very beginning several phycologists have made their life long efforts to study taxonomy of the members of Volvophycota all over the world. But no such attempt was ever made to make a detailed taxonomic investigation of the algal of this phylum from any part of Pakistan. Therefore, the present research program was carried out. Это и многое другое вы найдете в книге Taxonomy of Green Algae from North-Eastern Areas of Pakistan: II (Waqar Ul Haq,Ali Zarina and Mustafa Shameel)
