Virginia strawberry (Fragaria virginiana), colorized SEM (x 62, the line represents 500 microns). Strawberry is a 'false-fruit' insomuch as the red pulpy part is in fact the receptacle of the flower, carrying the fruits (or achenes, grains at the surface). The grain is contained in the achene. Here, it is the achenes of the growing strawberry that are visible. Virginia strawberry is the wild strawberry of the United States and Canada. Introduced in France in the 18th century, it was hybridized with the Chilean strawberry (Fragaria chiloensis) to create our existing garden strawberries. Virginia strawberry (Fragaria virginiana) > Wild strawberry plant > Strawberry plant > Rosaceae > Eudicotyledon > Angiospermae > Plant. Under a low magnification of only 62x, this scanning electron micrograph (SEM) depicted a view of a seed clustered exterior of a commonly growing wild strawberry, Fragaria virginiana, that was found growing in Lullwater Park, inside the Decatur, Georgia suburbs. The F. virginiana fruiting bodies are very similar to the more familiar, store-bought varieties, and those who've tasted these fruits say that they're quite delicious. The wild strawberry is considerably smaller than the store-bought species, which are actually hybrids from a cross between themselves, and those which commonly grow in Europe. Strawberries are one of the few fruits, whose seeds are located on the exterior of their ripening ovaries. The purpose of the sweet fruit is to act to entice larger animals, who after ingesting the fruit, and its accompanying seeds, deposit their waste containing the ingested seeds, thereby, dispersing the potential progeny of the fruiting plant.
