The non-degradability of sporopollenin is attributed to: |
Its resistance at very high temperatures. The absence of enzymes that can degrade it. Its ability to withstand strong acids. All of the above |
All of the above |
The correct answer is Option (4) -All of the above Sporopollenin is considered the hardest substance in the plant kingdom. It is a highly durable and resistant material that makes up the outer layer of pollen grains and spores. Sporopollenin is known for its exceptional stability and resistance to various environmental conditions. It can withstand strong acids, high temperatures, enzymes, and other degrading agents, making it highly durable and long-lasting. Due to its robust nature, sporopollenin helps protect the genetic material inside pollen grains and spores during dispersal and ensures their successful reproduction. Pollen grains are well-preserved as fossils because of the presence of sporopollenin. Therefore, sporopollenin is the hardest substance in the plant kingdom.
