Changes in coenobia size and coenobia number during the cell cycle of synchronous cultures of Scenedesmus quadricauda. Changes in coenobia size (solid lines) and coenobia number (dotted lines) during the cell cycle of synchronous cultures of wild type (A), selenite resistant (B), selenate resistant (C) and selenite+selenate resistant (D) strains of Scenedesmus quadricauda grown in the presence of 50 mg Se × l-1 of selenite or selenate or selenite+selenate. Data are presented as means ± S.D. of triplicate experiments.
