Summary
| Description |
English: Confocal laser scanning fluorescence micrograph of thale cress anther (part of stamen). The picture shows among other things a nice red flowing collar-like structure (just below the anther) that makes it somehow similar to jellyfish. However, an intact thale cress stamen does not have such collar, this is a fixation artefact: the stamen has been cut below the picture frame, and epidermis (upper layer of cells) of stamen stalk has peeled off, forming a non-characteristic structure.
Deutsch: Konfokale Laser-Scanning-Fluoreszenz-Mikroskopaufnahme des Staubbeutels einer Ackerschmalwand. Das Bild zeigt u.a. eine schöne rote, fließende, kragenartige Struktur (direkt unter dem Staubbeutel), die eine gewisse Ähnlichkeit mit Quallen aufweist. Ein intaktes Staubblatt der Ackerschmalwand weist jedoch keinen solchen Kragen auf, sondern ist ein Artefakt der Fixierung: Das Staubblatt wurde unterhalb des Bildrahmens abgeschnitten, und die Epidermis (obere Zellschicht) des Staubblattstiels hat sich abgeschält, wodurch eine uncharakteristische Struktur entstanden ist.) |
