Distribution of subcellular luminescence in the five morphological stages (I-V) of cells in early day phase and night phase. Each of the 10 cells shown was positioned on the suction pipet, seen on the left, and photographed. The cell was then stimulated with acid and a video-IIT record of the resulting bioluminescence was made. Polaroid photographs of the video screen made during real-time play back are shown below each of the photomicrogr

Distribution of subcellular luminescence in the five morphological stages (I-V) of cells in early day phase and night phase. Each of the 10 cells shown was positioned on the suction pipet, seen on the left, and photographed. The cell was then stimulated with acid and a video-IIT record of the resulting bioluminescence was made. Polaroid photographs of the video screen made during real-time play back are shown below each of the photomicrographs. In the night-phase stage I and II cells shown here, the nucleus was on the side of the cell closest to the objective and corresponds to the dark region seen in the IIT micrographs of bioluminescence. In the night-phase stage III cell, the nucleus was on the far side of the cell and no dark region was apparent. The night-phase stage V cell exhibits the morphology seen before aplanospore formation. For the two early day-phase aplanospores shown, the one on the left had its nucleus closest to the objective, while the nucleus of the right-hand aplanospore was on the far side of the cell, which accounts for its apparently dim perinuclear glow. Note that the chloroplasts which cover the surface of day phase cells migrate into a tight clump in the perinuclear region during night phase (Swift & Durbin, 1971; Sweeney, 1981). Scale, 50.
