Description

Scanning electron micrograph of Helianthus annuus (Sunflower) pollen. These specimens have been acetolyzed to remove cytoplasm and pollenkit in order to reveal the intricate wall structure. This is part of a large image collection of scanning electron micrographs of pollen samples. Images of a particular species are grouped together. However, to find images and groups of images from other species, please search for the the name of the contributor, Louisa Howard.
