Sporopollenin
Sporopollenin is a robust biopolymer found in the outer walls of pollen grains and spores. It is known for its exceptional resistance to degradation, making it one of the most durable organic materials in nature. This resilience allows pollen and spores to survive harsh environmental conditions, aiding in the reproduction of plants.
The structure of sporopollenin is complex, consisting of various long-chain fatty acids and phenolic compounds. Its unique properties not only protect the genetic material within but also play a crucial role in the dispersal of plants and fungi. This ensures the continuation of diverse ecosystems.
