Q. Describe Palynological Evidence?
Palynology is the study of pollen and spores. The taxonomic characters of pollen grains include wall structure, polarity, symmetry, shape and grain size. In angiosperms pollen grains are of two kinds viz. Monocolpate and tricolpate. Monocotpate pollen grains are boat shaped, have one long germinal furrow and one germinal aperture. This is characteristic of primitive dicotyledons and majority of monowtyledons. According to some palynologists the first flowering plants had monocolpate pollen grains. Tricolpate grains are globose, symmetrical, have three germinal apertures and are characteristic of advanced dicotyledons.
