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.
