Fig. 6

Photomicrographs of Linostomella vorticella from life (an) and after Hoechst 33342 staining (o). a–c, Various individuals to show the different body shapes and ratios of buccal length to body length, arrows mark the prominent paroral membrane. d, h, Left-lateral views of different cells, arrows mark the depression at posterior end of body. e, Detail of oral area, arrows mark the adoral zone of membranelles, arrowheads show the paroral membrane. f, Detail of cilia, arrows denote each basal body bears a cilium. g, Tiny cortical granules densely distributed between ciliary rows. i, Detail of the glabrous protuberance in oral cavity, arrowheads mark the fiber-like stripes. j, Food vacuoles with algae. k, Dorsal view of an individual full of food vacuoles, arrows mark the collecting canal. l, Contractile vacuole (arrows) near posterior end of body. m, Ventral view of a squashed cell, arrows indicate the glabrous protuberance, arrowheads mark different stages in the diastolic process of the contractile vacuole. N, Dorsal view of a cell, arrows mark the moniliform macronucleus. o, Hoechst 33342-stained individual to show the moniliform macronucleus. Abbreviation: Ma, macronucleus. Scale bars = 60 μm (a, d, e, k, m, n), 90 μm (b, h), 75 μm (c, l, o)
