Abstract
Acid resistant components of the pollen wall and tapetal membrane in flowering plants have long been known to be composed of sporopollenin—a highly resistant mixture of organic compounds. Recent light microscopy and cytochemical analyses have led to the recognition that additional organic compounds comprise a significant part of these anther structures. However, comparatively little consideration has been given to the inorganic composition of the pollen exine and the morphologically similar tapetal membrane. Electron microscopy allows the morphological characterization of components and, when coupled with energy dispersive x-ray analysis, offers the opportunity to characterize elemental composition.
