Question

Pollen grains are well preserved as fossils. Why?

Answer 1

Pollengrain contains an outer wall called exine. it is most resistant organic material nd can widstand high temperature. Due to the presence of sporopollenin pollen grains are preserved as fossils

Answer 2

Pollen grains have a two-layered wall.and the hard outer layer is called as exine and is made up of sporopollenin which is the most resistant organic material . It can withstand the high temperatures, strong acids, alkali and etc.... there is no enzyme which degrades sporopollenin . Pollen grains are well-preserved as fossils because of the sporopollenin.
