No enzyme known to degrade sporopollenin exists; the pollen grain's exine has germ pores where it's absent. Sporopollenin preserves pollen as fossils, and the exine exhibits varied patterns.
Non è ancora noto alcun enzima che degradi la sporopollenina. L'esina del granulo pollinico ha prominenti aperture chiamate pori germinativi dove la sporopollenina è assente. I granuli pollinici sono ben conservati come fossili a causa della presenza di sporopollenina. L'esina mostra una gamma affascinante di motivi e disegni.
| Text | No enzyme that degrades sporopollenin is so far known. {{c5::Pollen grain}}'s exine has prominent apertures called germ pores where sporopollenin is absent. Pollen grains are wellpreserved as fossils because of the presence of sporopollenin. The exine exhibits a fascinating array of patterns and designs. |
