POLLEN  

Definition

  • Pollen are several-celled microgametophyte of seed plants enclosed in a microspore wall. Fossil pollen consists entirely of the microspore wall. The study of pollen is called palynology or pollen analysis and is an important aspect in reconstructing past climates. Paleoclimatic reconstructions by pollen analysis is possible because (1) pollen grains possess morphological characteristics that are specif to a particular genus or species of plant; (2) they are produced in vast quantities by wind-pollinated plants and are distributed widely from their source; (3) they are extremely resistant to decay; and (4) they reflect the natural vegetation at the time of pollen deposition, which can yield information about ast climatic conditions.
