Abstract

Volvocales and Chlorococales represent an important orders of aquatic phototrophs, it is interesting group resembles like animal as well as algae or plant. In this study, we aimed to revolutionized our knowledge and understanding of conventional taxonomy of different genus of order from Girna river Jalgaon region of Maharashtra, India. Sample were taken from three locations at Girna river. Twenty two species of Volvocales and Chlorococcales were observed under Light microscopic (LM), and identified till forms level. All members of Volvocales and Chlorococcales species were taxonomically determined and are described for the first time from these areas. They were listed and presented with morphological descriptions, dimensional information and photographic information. Green flagellates with elongate, ovoid, spindle-like shape cells, varying in length from 15 to 500 μm, and with one or two flagella originating within an anterior of the cell. Volvocales have two methods of locomotion involves helical rotation of the cell and most species exhibit, when swimming stops and other is wiggling method. Chloroplasts vary in shape, size, number per cell and pyrenoid type. The chloroplasts are grass-green and contain chlorophylls.
