Light and transmission electron microscopy of Leontynka pallida (a–e) and Leontynka elongata (f–j). Note the difference in the cell shape between the two species and the presence of a single (a, f, h) or two (b, d, g, i, j) eyespots. Lipid droplets were also detected within the cells (d, h, j). Abbreviations: bb – basal body; cv – contractile vacuole; e – eyespot; L – lipid droplet; m – mitochondrion; N – nucleus; n – nucleolus; s – starch. Arrows point to eyespots; asterisks mark plastid “bridges” connecting separate compartments; black arrowheads show membranous inclusions; white arrowheads point to thylakoids. Scale bars: a–c, f–g = 10 μm; d, i = 0.2 μm; e = 0.5 μm; j = 1 μm
