RM2BE0J71–Under a high magnification of 1421x, this scanning electron micrograph (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 colored blue-violet, accented by six bright yellow, pollen producing anthers, which sat atop the ends of their complimentary blue-violet filaments
RMMR5N8E–Replica of the first Microscope by Leeuwenhoek. Antonie van Leeuwenhoek who achieved up to 300 times magnification using a simple single lens microscope. He sandwiched a very small glass ball lens between the holes in two metal plates riveted together, and with an adjustable-by-screws needle attached to mount the specimen. Van Leeuwenhoek re-discovered red blood cells and spermatozoa, and helped popularise the use of microscopes to view biological ultrastructure. 1676,

RM2BE0J6C–At a very low magnification of only 12x, this scanning electron micrograph (SEM) depicts some of the ultrastructural details made visible of the surface of an unidentified wasps' nest. Note what appears to be a lamellated, or layered pattern, which was used by the nest builders in the construction of the hexagonally-shaped cells. Wasp nests are primarily composed of a mixture of masticated wood chips, and the salivary secretions of the female wasps, who chew and apply the mixture in a nest-building fashion unique to the specie of wasp. The nest is built around a configuration of hexagonal-shap
