  1. PalynologyMichael G. Simpson Palynology (Gr, palynos, dust) = The study of pollen and spores Why study? • Use as characters in phylogenetic analysis • Use in plant identification • Extant plants • Fossil plants • paleopalynology • past plant communities, climate, biogeography, migration

  2. What are they? Spore - haploid cell derived from sporganium via meiosis Pollen - immature, endosporic male gametophyte derived from male spores (microspores) in Seed Plants

  3. Pollen Nucleus No. binucleate versus trinucleate

  4. Pollen Storage Product starch versus oil

  5. Pollen Unit monad

  6. Pollen Unit tetrad tetrahedral tetragonal

  7. Pollen Unit tetrad decussate

  8. Pollen Unit polyad
