Microanatomy of Plant Tissues 

A gallery of confocal microscopy images by Jim Haseloff at the University of Cambridge. A wide variety of staining techniques has been adopted for plant specimens over the past 150 years. Many of the synthetic dyes used for plant microtechniques are highly fluorescent and many classical histological techniques unintentionally produce specimens that are highly suited for confocal microscopy. The digital controls of a confocal microscope allow for the clean separation of different fluorescent emission signals and the balancing of signal levels in different channels. Thus, fluorescent images of exceptional clarity and vivid color can be easily obtained.
