Abstract Thekamöbe. Lebensraum bei Zuchtbedingungen. Dreifache Zonierung der Protoplasten mit Pseudopodienfächer aus Filopodien und Plasmalamellen, Schale. Nahrungsaufnahme. Kern- und Zellteilung, Zystenbildung. Mit Zeitraffung.
The film describes the biology of Chlamydophrys minor (Rhizopoda, Testacea). The thecamoebae are shown in their artificial habitat: the water film on the surface of an agar plate. The most important features of their morphology are: triple stratification of the protoplast; one nucleus with a spherical nucleolus in the centre; contractile vacuoles at the periphery of the "pheosomal zone"; and filopodia and lamellae of pseudopodial cytoplasm in a fan-like arrangement. The existence of a test immediately adjacent to the cytoplasm is shown by experimental plasmolysis. Locomotion and ingestion of food (phagocytosis of bacteria) are then demonstrated. Nuclear and cellular division are documented in the following three scenes. Finally, one may see the development of cysts and their germination.
