Color enhanced scanning electron micrograph (SEM) of Buttercup pollen grains. This stunning image reveals the intricate detail of buttercup pollen. Each microscopic facet of this material has been shaped by millions of years of evolution to form the delicate yellow flowers of the buttercup. Members of the Ranunculus genus, buttercups grow in still or running water and provide food for the caterpillars of many butterfly species. Their vibrant, glossy yellow petals have been a popular part of the children's test for liking butter for generations. Magnification 700x when printed 12.7cm (KEYSTONE/SCIENCE SOURCE/Nano Creative)
