Abstract Grundlagen des plasmolytischen Experiments: Wasserentzug aus pflanzlichen Geweben durch hypertonische Lösungen; Ablösung des Protoplasten von der Zellwand; Reversibilität der Plasmolyse, konvexe und konkave Formen nach Art des Plasmolytikums; Hechtsche Fäden; Vitalitätstest der Zelle. Zytorrhyse an Mooszellen: Zellwand als semipermeable Membran für großmolekulare Lösungen; Eindellung der Zellwand.
Principles of the plasmolytic experiment: extraction of water from plant tissue by hypertonic solutions; detachment of protoplast from cell wall; reversibility of plasmolysis, convex and concave forms depending on the plasmolyte; Hecht's threads; cell vitality tests. Cytorrhysis in moss cells: cell wall as semi-permeable membrane for macromolecular solutions; inward bulging of the cell wall.
