Question

Pollen grains can be preserved as fossil because

• A. they vary from species to species.
• B. they have a wide variety of architecture.
• C. their wall is made up of sporopollenin.
• D. they exhibit a fascinating array of patterns and design.

Answer 1

Answer: (C)

Pollen grain has a outer covering called exine that is made up of a thick layer made up of sporopollenin. The exine is discontinuous in some regions where sporopollenin is absent. Also, sporopollenin is one of the most resistant known biological material. As a result, pollen grains can preserved as fossil.
