Exine of pollen grain

Vedclass · Answer

(A) The exine of the pollen grain is composed of a highly resistant organic material called sporopollenin. Sporopollenin is one of the most resistant organic materials known. It can withstand high temperatures and strong acids and alkali. No enzyme that degrades sporopollenin is so far known. Therefore,it protects the pollen grain from degradation and allows it to be well-preserved in fossil deposits.
