Daisy tears

I analyzed the yellow center of a daisy. it is composed of several flowers and each of them consists of several petals. the petals have a very organized structure. on the surface of the petals there are many balls that looks like tears. analysis of flowers by scanning electron microscopy allows a better understanding of their structure and the presence of allergens.
