AuBerdem erscheinen mineralische Ultrastrukturen im Auflichtbild oft durch organische Substanzen verhtillt. Man wird daher auch weiterhin auf herk6mmliehe Methoden wie Dtinnschliff-Untersuchung und Transmissions-Elektronenmikroskop nicht verzichten, sondern gezielt die jeweils gttnstigsten Methoden einsetzen, um die morphologische Betrachtungsweise auch in der Pal~iontologie fiber den Sichtbereich unseres Auges hinaus zu erweitern.

Metabolism in plant storage tissue slices
TL;DR: The tissue of resting plant storage organs can be activated by slicing into thin disks and incubation of these fragments in a moist atmosphere for different periods of time (“aging”) and a vigorous synthesis of various enzymes and structural proteins which enable the cell to greatly enhanced metabolic activities.

Genotoxic effects of crude juices from Brassica vegetables and juices and extracts from phytopharmaceutical preparations and spices of cruciferous plants origin in bacterial and mammalian cells
Fekadu Kassie,Wolfram Parzefall,S. R. R. Musk,Ian T. Johnson,Günther Lamprecht,Gerhard Sontag,Siegfried Knasmüller +6 more
TL;DR: The present findings clearly indicate that cruciferous vegetables contain DNA damaging constituents and raise the question whether greatly increased consumption of Brassica vegetables or their concentrated constituents as a means for cancer prevention is indeed recommendable.
