why does the pollen grain not disintegrate in adverse environmental condition
Asked by begomhamida567 | 12 Jun, 2021, 04:52: PM
Expert Answer
The exine is the outer covering of pollen grain which is highly sculptured with sporopollenin; a chemically inert polymer of carotenoid ester which is highly resistant to degradation by any enzyme, as known so far. It can withstand extremes of temperature and desiccation.
