Figure 5
(a) Culture flasks of RCC1774 (left) and HCIR111A (right) showing their distinct colour. (b,c) Colour light micrographs of RCC1774 (a) and HCIR111A (b) using differential interference contrast (DIC). (d,g) Black and white light micrographs of RCC1774 (d) and HCIR111A (g) under DIC. (e,f) The same cells of RCC1774 (e,f) and HCIR111A (h,i) seen under epifluorescence using blue (e,h) and green (f,i) excitation. Arrows indicate three large or dividing cells that brightly fluoresce under blue (note the curtain-like organization of thylakoids) but comparatively less under green excitation. (j) Box plot chart showing the cell size distribution (n = 100) for each strain. The bold line indicates the median.
