Caption: Light micrograph of Desmidium swartzii freshwater filamentous green algae, showing intense red autofluorescence of the chloroplasts. Cells are triradiate in end view. The filaments appear to be twisted because the axes of adjacent cells are offset by a slight angle. Culture material of the Culture Collection of Algae at the University of Cologne, Germany. Microscopic contrast method : Fluorescence contrast with blue excitation. Magnification 200x when printed at 10 centimetres wide.
