Abstract Aufsammeln von Zieralgen im Hochmoor und Herstellung steriler Kulturen; Grünalge Micrasterias als Modellzelle für Transmissions-Elektronenmikroskopie: Präparation des Objektes mit Fixierung, Einbettung in Kunstharz, Herstellung von Ultradünnschnitten, Nachkontrastierung sowie eigentliche Elektronenmikroskopie (Bildherstellung und Auswertung).
In this film the collection of Desmids (especially Micrasterias) in peat bogs and the following establishments of semi-sterile algae cultures is shown. With the green alga Micrasterias as a modell-cell the different preparative steps for transmission-electron microscopy e. g. fixation, embeding into plastic, ultrathin sectioning, staining and electron microscopy (taking of pictures and its interpretation) is demonstrated.
