Several karyosomes in Noctduca (E) hold the chromatin, the rest of the nucleus is filled with "achromatic " granules. In Tetramitus chilomonas (D) the chromatin is scattered throughout the cell; the lighter-colored body in the centre of the cell is the homologue of the deeply stained central body in Euglena (C)..
