Light microscope footage of Euglena viridis algae, showing the beating flagellum and sometimes metabolic movement of the elongate cells. In this preparation the remaining water film is thick enough to ensure the undisturbed movement of the alga cells. Euglenoids are among the most ancient lineages of eukaryotic algae. Euglenoids display a surface structure composed of parallel ribbon-like strips, running lengthwise down the cells. The algae contain Paramylon grains (a starch-like carbohydrate) as well as a characteristic red eyespot. Euglena viridis is photosynthetic, using the energy of sunlight to synthesize food. The eyespot is sensitive to light, allowing it to move towards sunlight. Microscopic contrast method used : differential interference contrast. Captured field width : 0, 23mm | |
