Image de Tradescantia

Description :

Magnified 202x, this scanning electron micrograph (SEM) revealed some of the morphologic ultrastructure found on the petal of an unidentified specie of "spiderwort" flower, Tradescantia sp.. In the background on the left, the centrally located stigma is visible. It is unto the stigma that the pollen is to land in order to pollinate the flower. The spiderwort's sap is very viscous, and when touched between the fingertips, the sap will stretch, much like the strands of a spider's silky web, hence the name, spiderwort.
