Sporopollenin cannot be degraded by enzyme; strong acids and alkali, therefore it is helpful in preserving pollen as fossil.
Pollenkitt – Help in insect pollination.
Cellulosic Intine – Inner sporoderm layer of pollen grain known as intine made up cellulose & pectin.
Oil content – No role is pollen preservation.
