Colour enhanced scanning electron micrograph (SEM) of Spiderwort petal and a single pollen grain. Magnification 1421x. This SEM revealed some of the morphologic ultrastructure found on the petal of an unidentified specie of spiderwort flower,Tradescantia sp. Note the myriad of textures comprising the petal's surface,a structure that is actually a modified leaf. A single pollen grain was at rest atop the petal in this field of view. The three petals of this particular species of Tradescantia were coloured blue-violet,accented by six bright yellow,pollen producing anthers,which sat atop the ends of their complimentary blue-violet filaments | |
