Question

Sporopollenin can protect pollen grains from adverse environmental conditions and also maintain their viability over several years.

• A. True
• B. False

Answer 1

The correct option is B

False

Sporopollenin is a highly resistant substance which protects the pollen contents against adverse environmental conditions during the viable period of pollen. Beyond this period pollen grain cannot remain viable in nature. Therefore, sporopollenin cannot maintain pollen viability beyond their usual viability period.
