German
Küchenzwiebel (Neusiedler Rote). Nach anfänglicher Konkav- und anschließender Konvexplasmolyse in 0,65 mol KNO[3] (6 Versuche) und 0,5 mol LiCl (1 Versuch) quillt das Protoplasma der Außenepidermis durch Eintritt von Ionen kappenartig auf. Der Kappenbildung geht häufig eine Ansammlung des Protoplasmas um den Zellkern voraus (Systrophe). Zeitraffung.
