Extended Data Figure 10 : Light micrographs and TEM showing food vacuoles in Nematodinium sp.

From: Eye-like ocelloids are built from different endosymbiotically acquired components

Extended Data Figure 10

a, Differential interference contrast light micrographs showing a cell with prey (P) visible as green tinted food vacuole. b, Differential interference contrast light micrographs showing a cell in which the condensed dinoflagellate-type nuclei (n) are visible as birefringent chromosomes both in the predator and in the prey. c, Differential interference contrast light micrographs of a Nematodinium sp. cell containing digested prey (arrowhead) and co-occurring with potential prey, a smaller dinoflagellate. d, TEM showing a food vacuole inclusion consisting of a bolus of discharged trichocysts. e, TEM of undischarged dinoflagellate-type trichocysts showing their characteristic square shape in transverse section. f, TEM of discharged dinoflagellate-type trichocysts showing their characteristic striation pattern in longitudinal section.
