Morphology of Frontonia vernalis population IPSal + b (Neotype). a Schematic drawing of the ventral side; b live cell bearing Chlorella-like (Ch) endosymbiotic algae; c nuclear apparatus after Feulgen stainining, showing the macronucleus (Ma) and several micronuclei (Mi); d closer view of Ma and “compact type” Mi after Feulgen staining; e detail of Mi morphology and location in live cell, plus detail of Chlorella-like endosymbiont (Ch). CC – collecting canals; CV – contractile vacuole; OA – oral aperture; P – phagosomes; PrS – preoral suture, PtS – postoral suture; Tc – trichocysts. Bars stand for 50 μm (a-c), 10 μm (d), 5 μm (e)
