Pollen grains are able to tolerate extremes of temperature and desiccation as its exine is made of

A

Cutin

B

Suberin

C

Sporopollenin

D

Callose

Text Solution

Verified by Experts

The correct Answer is:
C
Exine is outer layer of pollen grain which is acetolysis resistant layer. It is also resistant to physical and biological degradation. Because of this property of exine , pollen grains are found well perserved for long periods in fossil deposits
