Q6 of 26 Page 1

During an excavation assignment, scientists collected pollen grains of a plant preserved in deeper layers of soil. Analyse the properties of pollen grains which help in the fossilization.

Fossilization is the process by which any plant or animal becomes a fossil.


Pollen grains have an outer layer called exine, it is made up of a highly decay resistant chemical called Sporopollenin. Presence of this chemical makes it possible for a pollen grain to withstand high temperature, strong acids, strong winds and bacteria etc. thereby helping in the fossilization of the pollen grains.
