A Single Pollen Grain (IMAGE) Arizona State University Caption A single pollen grain. The image was taken using a scanning-laser confocal microscope. These microscopes take many images of a sample at different depths. Each image, or as we call them slice, is saved and later the entire group of images are put back together using a computer. The final image has much more detail than a standard microscope. Image by CJ Kazilek Credit Courtesy: Arizona State University Usage Restrictions Image courtesy of Arizona State University (ASU).
