Abstract In cells of a culture of the large diatom Ditylum brightwellii (T. West) Grunow acclimated to faint light (17 μmol photons/(m 2 s)), numerous chloroplasts are evenly distributed throughout the cell cytoplasm. After 10 min of exposure of algae to extremely high illumination (1100 μmol photons/(m 2 s)), their aggregates gradually form in the center of the cell, and their formation continues until the end of the 2-h exposure period. At light intensities of 510–935 µmol photons/(m 2 s) duri
