(B) The pollen grain wall consists of two layers: the outer exine and the inner intine. The exine is made up of a highly resistant organic material called $Sporopollenin$. $Sporopollenin$ is one of the most resistant organic materials known. It can withstand high temperatures,strong acids,and alkali. No enzyme that degrades $Sporopollenin$ is so far known. Therefore,it protects the pollen grain from environmental stress and decay.

Which substance provides protection to pollen grains against high temperatures?
