Fig. 2 in Bumps on the back: An unusual morphology in phylogenetically distinct Peridinium aff. cinctum (= Peridinium tuberosum; Peridiniales, Dinophyceae)

Fig. 2 Flagellated cells of strain GeoM*979. a‒f Light microscopy, g‒m scanning electron microscopy, a‒d images taken from the same cell. a Dorsal view. b‒c Chloroplasts (as inferred from autofluorescence) at two different focal planes, note the space occupied by the nucleus. d Cell nucleus with chromosomes (as inferred from astra blue staining). e Ventral view of living cell. f Empty theca (mirrored) portraying cellular plates on the ventral side. g Apical view. h Dorsal view. j Ventral view. k Antapical view. l Right lateral view. m Left lateral view. Plate labelling follows the Kofoidean notation, n′: apical plate; n′′: precingular plate; n′′′; postcingular plate; n′′′′: antapical plate; na: anterior intercalary plate; sp: posterior sulcal plate. Scale bar= 10 µm
