Abstract
The cells from actively dividing cultures were fixed with an hourly interval for a period of 24 hours. The formation of semi cell and its ornamentation was studied. The process of cell division, the development of the typical cell ornamentation and the time taken for its completion were all recorded. The total period for the development of newly formed semicell was from 3—4 hours after beginning of the light. However the actual separation of newly formed cells usually took another 4 hours to achieve in all the species employed under present investigation. It was also found that a given cell would, at least under the imposed conditions, divide at best only once in every 24 hours as was also shown previously (Schulle 1975) in the desmid Staurastrum. During the present studies, Closterium acerosum, 6 species of Cosmarium (C. bioculatum, C. botrytis, C. contractum, C. cucumis, C. formosulum and C. subtumidum), Euastrum verrucosum and Staurastrum gracile were studied for their cell division under SEM.
