Sporogenesis and Pollen Grain Formation

  • Brigitte Buchen
  • A. Sievers
Part of the Cell Biology Monographs book series (CELLBIOL, volume 8)


Pollen grains and the spores of nonseed vascular plants1 develop from diploid somatic cells in a largely identical way. Ultimately, the cells are characterized by a highly ordered cell wall, the so-called sporoderm (Figs. 1 and 2). Both the chemical and the principal ultrastructural features of sporoderms show little Variation in different taxa, although the sculpture, number, and thickness of the individual wall layers display species-specificity. Fig. 3 shows a schematic cross section of a sporoderm and the surface view of a tectum, using in part the terminology proposed by Erdtman (1952).
