Fig. 1

Physiological changes in C. merolae cells grown in the flat-plate culture apparatus. a A picture of the flat-plate culture. Changes in number of cells and turbidity of culture (b), photosynthetic and respiratory rates (c), and contents of starch and protein (d) during the flat-plate culture. Each value is an average ± standard deviation of triplicates (b–d). e Normarski differential interference contrast images of cells at 0, 1, 3, and 6 h in the flat-plate culture. f A schematic image of C. merolae cell indicating plastid and extra-plastid compartments. Measured transverse and longitudinal diameters of each compartment are also shown. Changes in area (g) and aspect ratio (h) of plastid and extra-plastid. Each value is an average ± standard deviation of measurement for 30 cells (g, h)
