Solution

The exine of the pollen grain is made of sporopollenin. Sporopollenin is one of the most resistant organic compounds. It can withstand high temperature, strong acids and alkalis and cannot be degraded by any of the known enzymes. Hence, it acts as a shield and protects the pollen grain from getting damaged.
